Disable Windows95 Plug&Play feature, if S58.3=1 ----------------------------------------------------------------------------- November 8, 1996 Release Note on Elite 2864(L) and Omni 288S, Version 1.14 ============================================================ 1. Fixed modem bugs: -------------------- 1) Special dialing feature: .Modem does not finish dialing of numbers specified after P modifier and hangs for a time specified in S7 register. For example when "ATDT9WP8W10-886-3-578-7045" is entered, modem will report "NO CARRIER". .When bit 4 or register S35 is set, the modem will not dial the default phone number while the user press the DATA/VOICE switch in synchronous operation mode. 2) AT command and response: .When "AT&FX0" command is entered, the modem will report connect message as "CONNECT 38400" instead of "CONNECT" only. .When "ATM2" command is entered, modem will turn speaker off when retrain happened in ZyCell mode. .The modem does not prompt the hint message and erase the flash memory directly while the user keyin the "ATUPX" command with "ATQ1" disabling sending result code. .When the "AT&N65" command is entered, the modem will report some additional blanks in the "Last Speed/Protocol" field of "ATI2" command. .When "AT&M2X0" command is entered, the modem will response garbage and one more CR after connect message "CONNECT ". .When direct mode "AT&M2" command is entered,the modem will not send file correctly with 8E1 in data state. .When "LF" is entered after "AT" command in escape state, modem does not response "OK" 3) Security function: .When the call and anwer modems are entered with "AT&K0" and "ATS0=1*G5" respectively, the call modem can not enter the call back number after the connection. .When two Elite modems entered with the "AT&F&T4*F1S2=61" and "ATS0=1 &T4*F1*G5" in call and answer mode respectively, the call modem can not read the remote configuration successfully. .When the level 2 security function is enabled, modem will request the user to key in the password with the "Password" prompt instead of "PassWord". Note that the "PassWord" prompt is used in ZyXEL U-series modem. 4) Physical layer stability: .ZyCell protcol can not accept any data from the remote site after the connect message. .When the "ATX6&N16&T1" is entered, modem will report "NO CARRIER" and modem will turn on CD when issue the "AT" command after the report. .Modem can not connect with Supra modem with V.34 mode under some worst line condition. .Modem will get a lower speed than the inital handshaking when the retrain procedues happened oftenly in data state. 5) Link Layer compatibility: .There is a compatbility problem with "Octocom" modem. When ZyXEL calls it with V.22bis/MNP4 mode, ZyXEL modem can not accept any data from it after the connect meessage be displayed. .In Italy, ZyXEL modem can only connect Digicom modem with error control mode under 26400 bps link speed. For 28800 bps link speed, the connection is non error control mode. .There are some characters will be missed in file transmission when software flow control XON/XOFF (&H4) is enabled. 6) V.25bis command set: .Modem will not support use profile 2 to make a connection with AS/400. 7) Error control procedure: .Improve the efficent in echo delay testing and file transfer with XMODEM protcol. 8) Diagnostic feature: When the call and answer modems are entered with "AT&F&T4&K3" and "AT&F&D0S0=1&T4" respectively, the TST LED of calling modem will turns on after the connection. 2. Fixed fax bugs: ------------------ 1) If user want to print a fax, user issue "AT+FZP" and there should be <1F> response from modem. But this does not happen and will cause problems in writing the application for this function. 2) Cannot receive a fax correctly after a V.34 data connection: 3) The modem will report incorrect result code to ZFAX when there are incomfing fax stored in DRAM and ZFAX try to retieve fax from modem. 4) Setting the modem with AT+FZF=1, 4 or 5 and DTR is off, the modem will answer the modem call instead of dropping the modem call. 5) When modem stayes in DRAM fax reciving mode (clsaa Z, +fzf=2) without RS-232 cable, modem can not accept AT command anymore after reciving a fax and plug in the RS232 cable. 6) When modem stayes in class Z service, modem can not make an outgoing data call. 3. Added new feature: --------------------- User can issue an "ATI12" command to get the physical layer parameters choosed in V.34 mode. This information is reliable only in the escape state. Since the Near End echo and Far End echo reports are not ready, they will be filled with "-xx.x" and will be implemented asap. One of the example is as following: ATI12 ZyXEL MODEMS PHYSICAL LAYER STATUS REPORT Modulation mode = V.34 Tx Carrier = 1600 Hz Rx Carrier = 1800 Hz Tx Baud Rate = 2400 Baud Rx Baud Rate = 2400 Baud Tx Bit Rate = 16800 bps Rx Bit Rate = 12000 bps Tx Power = -11.0 dBm Rx Level = -24.3 dBm Phase Jitter = 0.0 degree Frequecy Offset = 0.0 Hz SNR = 24.1 dB Round Trip Delay = 5 ms Near End Echo = -xx.x dB Far End Echo = -xx.x dB Nonlinear Encoder = on Nonlinear Decoder = off Tx Shapping = min Rx Shapping = min Trellis Encoder = 64 state Convolutional Decoder = 16 state Tx Filter Index = 8 Remote Tx Filter Index = 0 Tx Precoder Coefficients = 0 0 0 0 0 0 Remote Tx Precoder Coefficients = 0 0 0 0 0 0 ----------------------------------------------------------------------------- August 1, 1996 Release Note on Elite 2864(L) and Omni 288S, Version 1.13 ============================================================ 1.

Fixed modem bugs: --------------------- 1) Failed to work with the external sync clock: In the external synchronous clock (AT&X1) mode, the modems could connect to each other but had a lot of bit error. 2) The O288S firmware could not recognize the incoming ring signal in Germany. 3) Modem hang when security function enabled: When the security function was enabled by AT*G1 or AT*G2 and the entered password was wrong, the modem should hang up and report "NO CARRIER". But the modem hang in an unknown state. 4) Incorrect password response in security function: When security function was enabled by AT*G5, the echoed password was followed by "" instead of "". 5) Abnormal hang-up when security function was enabled: When the security function was enabled, the modem could not perform analog loop back test by AT&T1 command. The modem would hang up and report "NO CARRIER" immediately after connection made by "AT&T1" command. With ATI2 command, the disconnect reason was shown as "Security Check". 6) Wrong break handling: After pressing the control-break key, the TXD LED lights up for a very short time and the RXD LED lights up for a longer time. When the control-break key was pressed again, only the TXD LED lights up but the RXD LED remains off. 7) Did not report the first RING: For example, the auto-answer mode was enabled by setting S0=1. When the first ring signal came, the modem went off-hook directly and starts to handshake without reporting "RING" to the DTE. 8) Compatibility problem with Penril modem: When the modem was connecting with the Penril modem, the handshaking would fail during the phase 2 of V.34 hand shaking procedure. 9) Wrong help message: If the multi-language feature of Germany version was enabled (S63=1), a wrong message "&N61 V.34b 31200" would be shown on screen with "AT&$" command. 10) Wrong indication of AA LED: The indication of AA LED was incorrect when the modem was set by the following command sequence: . AT&FS1=1&WZ : . AT&FS0=1 : AA LED lights on and indicates auto-answer mode. . ATZ : AA LED lights on but the S-register S0 is equal to 0. 11) Failed to respond to the ATX0D command: When "ATX0D;" command was entered, modem would hang and fail to accept the AT command. 12) Could not detect incoming ring signal: After executing "ATDxxxx;" and then "ATH" command, the modem would not be able to recognize the incoming ring signal. 13) Failed to dial with the synchronous V.25bis command: When the modem started dialing with the V.25bis "CRN" command, the dialing digits did not go through and then modem went on hook. 14) Failed to perform the analog loopback with self-test (AT&T8) in the non-error control mode (AT&K0). 2. Fixed fax bugs: ------------------ 1) Wrong result with the "ATI2" command after FAX send/receive: After a fax connection, with the "ATI2" command, the modem reported the last baud rate with the wrong value of "28800". 2) Improved reliability of V.21 HDLC receiving. 3) The compatibility problem with Panasonic fax machine: When the FAX machine did not send the ANSWER tone, the modem would disconnect the outgoing call instead of sending out the fax. 4) The problem of the Postscript FAX receiving/printing fixed. Postscript printing margin can be configured by paper type. 3. Fixed voice bugs: -------------------- Incorrect RI lead indicator of RS232: When modem went off-hook to answer the incoming call and play the voice greeting message in the voice mode, RI lead (pin 22 of RS232) kept high. Even aborting or terminating the voice playing, RI was still high. 4. New modem features: ---------------------- 1) Support Germany message display for commands: . ATI2 : report link diagnostic status . AT&Vn : view current active or user profile settings . AT#B3 : measure the ring cadence . ATDL : dial the last-dialed number 2) When the DTE speed was set to 19200, the highest connection rate would be limited to 19200 bps. 5. New fax features: --------------------- A fax protocol capture utility was implemented for debugging the FAX compatibility problem. This feature is not available for the FAX direct printing mode. S76: bit0 = 1 FAX response capture enabled bit1 = 1 FAX command capture enabled bit2 = 1 V.21 HDLC Tx/Rx capture enabled Use "AT+FZX?" command to show the captured log on terminal. 6. New voice features: ----------------------- 1) Add three sampling rate : 7200, 8000, 11025 bps 2) Add three digital compression algorithm : DVI ADPCM, A-law PCM, Mu-law PCM. 3) The command "AT+VSM=?" will show you how to use these new features. AT+VSM=? 2 ;ZyXEL ADPCM ;2Bit ;(7200,8000,9600,11025) 3 ;ZyXEL ADPCM ;3Bit ;(7200,8000,9600,11025) 30 ;ZyXEL ADPCM ;3Bit ;(7200,8000,9600,11025) 4 ;ZyXEL ADPCM ;4Bit ;(7200,8000,9600,11025) 40 ;DVI ADPCM ;4Bit ;(7200,8000,9600,11025) 80 ;A-law PCM ;8Bit ;(7200,8000,9600,11025) 81 ;Mu-law PCM ;8Bit ;(7200,8000,9600,11025) OK For example, to set DVI ADPCM with 8000 sampling rate, you use the command: AT+VSM=40,8000 The power on default sampling rate is 2Bit ADPCM with 9600bps. Known bugs of v1.12: ("very sorry, very sorry - it's not perfect yet") These bugs were recognized on March 14th, 1996: ------------------------------------------------------------------------ 1) The modem has problem with 11-bit character length. 2) Remote configure (*Wab) fails over V.22bis connection. 3) Security function (*G3) fails and causes modem reset. 4) Connect with V.22bis (2400 bps) with MNP5 data compression will transfer no data - please disable MNP5 feature with ATS38.5=1 ----------------------------------------------------------------------------- Release Note on Elite 2864 Version 1.11 Jan. 26, 1996 1. Improved the V.34 performance. --------------------------------- 2. Fixed modem bugs: -------------------- 1) The "carrier lost 1" problem: When the modem is connected to a Rockwell chipset based modem on some long distance calls, the modem will drop the line immediately with disconnect reason shown "carrier lost 1". 2) Incorrect LED indication: The V34 LED does not turn on if "AT&N62" to "AT&N72" command is entered. The "V32b" LED will turn off if a V.32 connection is established with "AT&N4" command. 3) Can not connect on two wire leased line mode: If "AT&L1" command is entered, the modem will go on-hook and report "NO CARRIER" immediately after connection. 4) Wrong leased line operation: If "AT&L1" command is entered, modem will go to handshaking procedure immediately. 5) Incorrect response for numeric form result code (ATV0): If "AT&K0&N14V0" command is entered, modem reports connect message as "10" instead of "10" after connection. 6) Unable to use V.25bis command set. 7) Sometimes in data state, the modem does not disconnect when DTE drops the DTR signal. 8) Impoved the reliability of recognizing the dial tone, busy tone and ring signal in Italy. 3. Fixed fax bugs: ------------------ 1) Incorrect response: Modem reports "+FHNG:70" followed by "NO CARRIER" while the incoming call is a voice call. 2) Some compatibility problems of class 1 commands with Win95. now the modem responses to the AT+FCLASS=? inquiry with the string "0,1,2,2.0,6,8,Z" 4. Fixed voice bugs: -------------------- 1) Fix the problem of BUSY tone detection of Italy: In Italy, the modem does not recognize the busy tone in voice mode. After recording a message, the modem does not go on-hook and continue to record the busy signal. 2) Improved the VCON reliability. 5. Added new features: ---------------------- 1) Some new user friendly commands: ? or $ Basic command summary help. &? or &$ Extended AT& command summary help. *? or *$ Extended AT* command summary help. #? or #$ Extended AT# command summary help. +? or #$ Extended AT+ command summary help. S? or S$ Show complete register list Sxxx=? Show the function of Sxxx register. Sxxx=$ Show the function of Sxxx register. 2) Multi language support: Right now, only two languages are implemented. If the value of S63 equals 1, the summary help is displayed in German. If the value of S63 equals 0, or any value other than 1, the summary help is displayed in English. [Note] . Right now, not all the information pages are available in both languages. So the help display is 'a bit' mixed sometimes. But this will be filled up with the correct language as soon as possible. 3) Report "DATA or FAX" before showing connect message: If bit7 of register S57 is set (default is reset), an additional connect message will be displayed on the screen. The additional message is "DATA" or "FAX" for data or fax connection respectively. For example, AT+FCLASS=1 AT+FAA=1 example 1: DATA CONNECT 115200/V34 28800/V42b/SREJ example 2: FAX CONNECT 4) The capability of fax receiving in class 6 is configurable. ============================================================================= Release Note on Elite 2864 Version 1.10 Dec. 22, 1995 1. Fixed modem bugs: -------------------- 1) Improper remote configuration: The local modem can not read or write the remote modem's profile on connection. (Note: Remote configuration is not inter-operable between an Elite 2864 and a U-1496 series modem. The Elite 2864 has more S-registers and some S-registers have different meaning.) 2) AT&T6 (initiate remote digital loopback) does not work. 3) Fail to recognize the dial tone of some PABXs: During dialing, the modem reports "NO DIALTONE" when the dial tone is not a continuous signal (with ON/OFF cadence). 4) Incorrect LED indication of dialing, handshaking and retrain: The V32b LED does not flash on and off for 1/2 second each to indicate that the modem is dialing. Neither do the V34 and V32b LEDs flash on and off for 1/2 second each to indicate that the modem is in handshaking or retrain. 5) "ATM3" does not work: With the "ATM3" command, the dialing tone is still heard from speaker. 6) Type 1 security function does not work (the *G1 and *G2 commands). 7) Does not support up to 50 passwords in security function: For example, in *G4 setting, the modem is not able to detect any password at location from #10 to #49. 8) Unable to recognize ring signal on some bad local loop lines. 9) Incorrect repeat dialing function: When bit0 of S38 is set, the modem will not dial the same number again while the modem reports "BUSY" after dialing. 10) Incorrect cyclic dialing: When bit3 of S44 is set, the modem will not dial the second number while the modem reports "BUSY" after dialing. 2. Fixed fax bug: ----------------- 1) Incorrect LED indicator: When "AT+FCLASS=6" command is entered, the V34 LED turns off in multi-auto mode (AT&N0). 3. Fixed voice bug: ------------------- 1) Sometimes the modem hangs after issuing to finish playing voice. 4. Add new features: -------------------- 1) Set the dial back timer S64 for security call back function: (default=0, in seconds) With level 2 security, the answer modem will disconnect the line if the password has been found in its pre-stored acceptable list. The answer modem will dial back the phone number corresponding to the dial-in password, when the dial back timer (containded in S64) is reached. If the content of S64 violates the PTT regulation, the dial back timer will be automatically set to the value defined in PTT regulation. S64 can be used to control the dial-back waiting time to avoid dialing back too quickly that the calling modem's line is still busy. ============================================================================= Release Note on Elite 2864 Version 1.09 Dec. 8, 1995 1. Fixed modem bugs: -------------------- 1) Fail to recognize the Italian dial tone. 2) Failure in dial tone monitoring: When "ATH1" command is entered, the modem goes offhook but there is no dial tone coming from the modem's internal speaker. 3) Incorrect response for numeric form result code (ATV0): For example, when "AT+FCLASS?" command is entered, modem responds with "00" instead of "00" in numeric form. 4) Problem on forcing V.22bis retrain: In V.22bis escape state, when "ATO1" command is entered to force the modem to request a retrain, the connect message shows "V.32 9600T". And sometimes the retrain fails. 2. Fixed fax bugs: ------------------ 1) Problem on fax reception: Sometimes the top portion (the first half inch) of the received page is chopped off when the receiving speed is 14400bps. 2) The AT+FZF=1 setting is not saved with AT&W command. 3. Add new fax feature: ----------------------- 1) The local ID string (AT+FLI=) can be saved to EEPROM with AT&W command. 4. Add new voice features: -------------------------- 1) Some programmers need the feature to enable the speaker when recording from telephone line. In this version, we let users use VLS=18 (16+2, speaker and Telco Line) to enable the speaker. 2) Some programmers also report that the transmit level of Tone (+VTS) and Voice (+VTX) are different. In this version, we let users set the transmit gain separately, AT+VGT for Voice and AT+VGN for Tone. The default value of AT+VGT is 128. The default value of AT+VGN is 60. 3) In this version, users can use s60 bit 4 to disable the Telco line playback AGC. 5. Important notes for voice programmers: ---------------------------------------- From version 1.07, the Near Echo Cancellation is disabled as the default setting, this decreases the sensitivity and reliablity of DTMF detection when playing voice message. Set the s60 bit 7 will enable the NEC ! ============================================================================= Release Note on Elite 2864 Version 1.08 Nov 27, 1995 1. Improved V.34 performance: ----------------------------- 1) Solve the "carrier lost 1" problem: When connected with a modem employing Rockwell's chipset, after about 10 minutes of connection, the modem will drop the line with disconnect reason shown "carrier lost 1". 2. Fixed modem bugs: -------------------- 1) Cannot report "BUSY" while waiting for the first and second dial tone: If bit6 of S57 is set, the modem will report "BUSY". If bit6 of S57 is reset (default), the modem will report "NO DIALTONE" 2) Problem with V.23 mode connection: The modem will hang-up within 5-6 seconds of V.23 mode connection. 3) Wrong change of S-register: When "AF+FCLASS=0" command is entered, the S register S19 will be cleared. 4) Cannot transfer file using XON/XOFF control: Modem hangs up the call when using XON/XOFF flow control for file transfer. And the disconnect reason shows "Local Hang Up". 3. Fixed fax bugs: ------------------ 1) Fail to detect busy tone: After dialing out the number, the modem does not report "BUSY" when the central office sends busy tone to modem. 2) Fail to go on-hook: If the modem answers a call with "AT+FCLASS=1;FAA=1;A" command and there is no response from remote modem, the modem will report "CONNECT", "ERROR" and then "OK". But actually the modem does not go on-hook. 3) Wrong LED indicators: If DRAM is installed in modem and "AT+FZF=3" command is entered, the EC and SP LEDs keep on after pulling out the RS-232 cable. 4. Fixed voice bugs: -------------------- 1) Fail to switch off the power to telephone jack: If "AT+FCLASS=8" and "AT+VLS=1" is given, the loacl telephone is still powered after "AT+FCLASS=0" command is entered. 2) Wrong response to "AT+VSM" command: When "AT+VSM" command is entered with incorrect values, the modem does not respond with an "ERROR" message. 3) Both V34 and V32b LEDs are not turned off in voice mode. 5. Add new features: -------------------- 1) Support Russian CNI detection. 6. Note: -------- 1) Change the default value of ring volume control from "N5" to "N3". ----------------------------------------------------------------------------- Release Note on Elite 2864 Version 1.07 Nov 16, 1995 1. Improved V.34 performance. ----------------------------- 2. Fixed modem bugs: -------------------- 1) Wrong response to ATDT;H command: the modem doesn't hang-up after dialing the phone number. 2) Wrong response to AT&FX7S6=5&W1Z1 command: viewing the setting by AT&V, the modem responds with the default setting of X5 and S6=2, in stead of X7 and S6=5. 3) Wrong AT command entered in escaped state will cause hang: if any wrong AT command is issued in escaped state, the modem will not respond to any futher AT commands. Modem should be powered off and on to reset. 4) Modem hangs: when the modem is ringing and the RS-232 cable is pluged in, then the modem will not respond to any futher AT commands. Modem should be powered off and on to reset. 5) Unable to send data calling tone for V.32b/V.22b/ZyX19200/ZyX16800 modes. 6) Connection problem when calling tone enabled: When the calling tone is enabled (AT&F&N0S48.2=1), the connection made with U-1496 plus models can only reach 16800 bps (the 19200 bps connection is not possible). 7) Wrong LED display: When the modem is connected with ZyX 19200 or 16800 bps, the LED V34 and V32b are ON. That is OK. But when you enter "+++" escape command and then "AT" command, the V32b LED goes OFF. 8) The S14 register does not contain the exact value of the command AT*M0 and AT*M1. For example, with command ATZ1*M1&V, the display shows the value of S14 bit 0 is 0; with command ATZ1S14.0=1&V, the display shows *M0. 9) The supervisory password entry can take only 7 characters: Try setting for example password #8 but type more than 8 characters and you will get "ERROR". 10) Problem of connecting to host with 7 data bits, even parity and 1 stop bit protocol: There is a problem when you try to connect to the "telebanking" service, where 7E1 protocol is used. What is supposed to happen is that you enter the user ID followered by , and then the host prompts you for the password. The bug is as soon as a numeric digit is entered, it behaves like a has been entered as well, and the host prompts for the user-ID again. After 3 incorrect attempts, you are automatically logged out. 11) On the password table, for example setting *G4, the modem is not able to detect any password at location #10 to #49. 3. Fixed fax bugs: ------------------ 1) In direct fax printing mode (AT+FCLASS=Z and AT+FZF=0), when a data call comes, the modem serial port will hang. (Can't switch from parallel port to serial port.) 2) V34 and V32b LED doesn't goes off in FAX mode. 3) CD on immediately after dialing in FAX Class 1 mode. 4) In fax DRAM retrieing mode, the RS-232 RI signal is not sent to DTE when "RING" string is sent to DTE. 4. New fax printing feature: ----------------------------- 1) Support Postscript Printer. 2) Support HP DJ500 series Inkjet Printer. 3) Support Serial Port Fax Printing. 4) Speedup PCL Printing.

Usage of Direct Fax Printing via serial port: --------------------------------------------- 1) Connect modem to PC via the RS-232 serial port. 2) Use a terminal Software to communicate with Modem 3) Set Baudrate = Serial Printer's Maximum Baudrate. (For example, if the max. baudrate of your serial printer is 38400, please use 38400 for terminal software) 4) Setup S72. (0,1 for PCL, 2 for Postscript printer) 5) Set AT+FZF = 0. (Direct Fax Printing) 6) Set AT+FZT Value. (This value relies on the printer speed, baud rate of serial port and printing language (Postscript is faster than PCL). The principle on deciding this value is: PRINTING MUST BE FASTER THAN FAX RECEVING!!! Because in AT+FZF=0 mode, received data is sent to printer directly. Therefore, fax printing speed must be faster than fax receving speed. Otherwise the internal buffer will overflow and some scanlines must be discarded. First, you can try AT+FZT=150. If it is OK, then you can try 100, 64, 48, 32, 16 and 0 to get the optimal speed. This value depends on your printer's printing speed. 7) Setup S73. (Configure fax printing options, bit 0 must be 1 for serial printing) 8) If auto-receving is needed, please set S0=1. 9) Set AT+FCLASS=Z. (Enable Fax Printing) 10) Use AT&WZ to store current setting to profile 0. (Store All S-Regs and Baudrate Settings in EEPROM) 11) Connect modem to printer Via the RS-232 serial port. Note: 1) In Serial Printing Mode, only DTR flow control is supported. Please setup your printer to accept DTR flow control. 2) Because the modem's serial port type is of DCE type, the printer's serial port type must be of DTE type. If the printer's serial port is also of DCE type, a NULL MODEM adapter (or cable) is needed. <1> Modem in normal operation : RS-232 Cable Modem(DCE) <------------> PC(DTE) <2> Modem is connected to a DTE Serial Printer: RS-232 Cable Modem(DCE) <------------> Printer(DTE) <3> Modem is connected to a DCE Serial Printer: RS-232 Cable Modem(DCE) <--> Adapter <------------> Printer(DCE) 3) In order to achieve maximum throughput, please use the maximum baud rate your printer permits. 5. Fixed voice bugs: -------------------- 1). Playing problem with 3-Bit ADPCM data. 2). Increase the reliablity of VCON detection. 3). Enhance the voice quality of local telephone phone set. 6. Add new voice features: -------------------------- 1). When first playing through telephone line, the default setting is disable the Near Echo Cancellation. The users can enable this feature by setting the bit 7 of s60 to 1. ----------------------------------------------------------------------------- Release Note on Elite 2864 Version 1.06 Sep 13, 1995 1. Improved FAX V.17 receiving performance. 2. Improved FAX V.21 sensitivity. 3. Improved FAX printing quality. 4. New FAX feature: (1) Function of s73 bit3: Set S-register s73 bit 3 to 1 (ATS73.3=1) will enable direct FAX printing application to print longer FAX pages to LETTER size paper. For off-line DRAM receiving and printing application, if s73 bit 3 is set to 1 the printing driver will automatically and dynamically select a zooming factor and print the FAX pages to fit the selected paper size. The zooming factor depends on the page length of the received FAX. The default setting of this feature is on (s73 bit 3 is set to 1). (2) AT+FZL? command: Show FAX receiving log For example, No. Remote FAX ID Speed Pages Size Status Hardcopy Retrieved === ==================== ====== === ===== ====== ======== ========= 1 886-35-782439 * 9600 3 110k OK YES 2 1-714-693-8811 14400 2 90k OK Free DRAM Size: XXX Where "No" ------------- Session log number "Remote FAX ID" -- Sending FAX machine indentifier (TSI) "Speed" ---------- Fax receiving speed and resolution "*" - fine resolution "Pages" ---------- Number of pages "Size" ----------- Log size (number of bytes) "Status" --------- Receivig result , "OK" or error code "Hardcopy" ------- FAX printing status "Retrieved" ------ Retrieved by FAX software if marked "YES" (3) AT+FZP=nn command: Print the received FAX by specifying the session log number "nn". 5. Fixed bugs: * FAX CNG tone transmitting: Sometimes it works but sometimes it doesn't work. * Data calling tone: When the data calling tone is enabled and a connection is made to another modem, the remote modem will show the wrong connect message like "CONNECT 115200/V.22 1200/NONE", but acturally the connection is not successful. * AT*Pn: AT*Pn can not be saved to profile. For example, originally at&f&v shows *P11. When at*p9&w0z&v is issued, the modem still shows *P11 instead of *P9. 6. Improved performance on FRN (fast rate renegociation). ------------------------------------------------------------------------------ Release Note on Elite 2864 Version 1.05 Aug 14, 1995 Note: Version 1.03 and 1.04 are not formally released, their relase notes are accumulated here. 1.

Fixed modem bugs: -------------------- 1) Special dialing feature: .Modem does not finish dialing of numbers specified after P modifier and hangs for a time specified in S7 register. For example when "ATDT9WP8W10-886-3-578-7045" is entered, modem will report "NO CARRIER". .When bit 4 or register S35 is set, the modem will not dial the default phone number while the user press the DATA/VOICE switch in synchronous operation mode. 2) AT command and response: .When "AT&FX0" command is entered, the modem will report connect message as "CONNECT 38400" instead of "CONNECT" only. .When "ATM2" command is entered, modem will turn speaker off when retrain happened in ZyCell mode. .The modem does not prompt the hint message and erase the flash memory directly while the user keyin the "ATUPX" command with "ATQ1" disabling sending result code. .When the "AT&N65" command is entered, the modem will report some additional blanks in the "Last Speed/Protocol" field of "ATI2" command. .When "AT&M2X0" command is entered, the modem will response garbage and one more CR after connect message "CONNECT ". .When direct mode "AT&M2" command is entered,the modem will not send file correctly with 8E1 in data state. .When "LF" is entered after "AT" command in escape state, modem does not response "OK" 3) Security function: .When the call and anwer modems are entered with "AT&K0" and "ATS0=1*G5" respectively, the call modem can not enter the call back number after the connection. .When two Elite modems entered with the "AT&F&T4*F1S2=61" and "ATS0=1 &T4*F1*G5" in call and answer mode respectively, the call modem can not read the remote configuration successfully. .When the level 2 security function is enabled, modem will request the user to key in the password with the "Password" prompt instead of "PassWord". Note that the "PassWord" prompt is used in ZyXEL U-series modem. 4) Physical layer stability: .ZyCell protcol can not accept any data from the remote site after the connect message. .When the "ATX6&N16&T1" is entered, modem will report "NO CARRIER" and modem will turn on CD when issue the "AT" command after the report. .Modem can not connect with Supra modem with V.34 mode under some worst line condition. .Modem will get a lower speed than the inital handshaking when the retrain procedues happened oftenly in data state. 5) Link Layer compatibility: .There is a compatbility problem with "Octocom" modem. When ZyXEL calls it with V.22bis/MNP4 mode, ZyXEL modem can not accept any data from it after the connect meessage be displayed. .In Italy, ZyXEL modem can only connect Digicom modem with error control mode under 26400 bps link speed. For 28800 bps link speed, the connection is non error control mode. .There are some characters will be missed in file transmission when software flow control XON/XOFF (&H4) is enabled. 6) V.25bis command set: .Modem will not support use profile 2 to make a connection with AS/400. 7) Error control procedure: .Improve the efficent in echo delay testing and file transfer with XMODEM protcol. 8) Diagnostic feature: When the call and answer modems are entered with "AT&F&T4&K3" and "AT&F&D0S0=1&T4" respectively, the TST LED of calling modem will turns on after the connection. 2. Fixed fax bugs: ------------------ 1) If user want to print a fax, user issue "AT+FZP" and there should be <1F> response from modem. But this does not happen and will cause problems in writing the application for this function. 2) Cannot receive a fax correctly after a V.34 data connection: 3) The modem will report incorrect result code to ZFAX when there are incomfing fax stored in DRAM and ZFAX try to retieve fax from modem. 4) Setting the modem with AT+FZF=1, 4 or 5 and DTR is off, the modem will answer the modem call instead of dropping the modem call. 5) When modem stayes in DRAM fax reciving mode (clsaa Z, +fzf=2) without RS-232 cable, modem can not accept AT command anymore after reciving a fax and plug in the RS232 cable. 6) When modem stayes in class Z service, modem can not make an outgoing data call. 3. Added new feature: --------------------- User can issue an "ATI12" command to get the physical layer parameters choosed in V.34 mode. This information is reliable only in the escape state. Since the Near End echo and Far End echo reports are not ready, they will be filled with "-xx.x" and will be implemented asap. One of the example is as following: ATI12 ZyXEL MODEMS PHYSICAL LAYER STATUS REPORT Modulation mode = V.34 Tx Carrier = 1600 Hz Rx Carrier = 1800 Hz Tx Baud Rate = 2400 Baud Rx Baud Rate = 2400 Baud Tx Bit Rate = 16800 bps Rx Bit Rate = 12000 bps Tx Power = -11.0 dBm Rx Level = -24.3 dBm Phase Jitter = 0.0 degree Frequecy Offset = 0.0 Hz SNR = 24.1 dB Round Trip Delay = 5 ms Near End Echo = -xx.x dB Far End Echo = -xx.x dB Nonlinear Encoder = on Nonlinear Decoder = off Tx Shapping = min Rx Shapping = min Trellis Encoder = 64 state Convolutional Decoder = 16 state Tx Filter Index = 8 Remote Tx Filter Index = 0 Tx Precoder Coefficients = 0 0 0 0 0 0 Remote Tx Precoder Coefficients = 0 0 0 0 0 0 ----------------------------------------------------------------------------- August 1, 1996 Release Note on Elite 2864(L) and Omni 288S, Version 1.13 ============================================================ 1.

Fixed modem bugs: --------------------- 1) Failed to work with the external sync clock: In the external synchronous clock (AT&X1) mode, the modems could connect to each other but had a lot of bit error. 2) The O288S firmware could not recognize the incoming ring signal in Germany. 3) Modem hang when security function enabled: When the security function was enabled by AT*G1 or AT*G2 and the entered password was wrong, the modem should hang up and report "NO CARRIER". But the modem hang in an unknown state. 4) Incorrect password response in security function: When security function was enabled by AT*G5, the echoed password was followed by "" instead of "". 5) Abnormal hang-up when security function was enabled: When the security function was enabled, the modem could not perform analog loop back test by AT&T1 command. The modem would hang up and report "NO CARRIER" immediately after connection made by "AT&T1" command. With ATI2 command, the disconnect reason was shown as "Security Check". 6) Wrong break handling: After pressing the control-break key, the TXD LED lights up for a very short time and the RXD LED lights up for a longer time. When the control-break key was pressed again, only the TXD LED lights up but the RXD LED remains off. 7) Did not report the first RING: For example, the auto-answer mode was enabled by setting S0=1. When the first ring signal came, the modem went off-hook directly and starts to handshake without reporting "RING" to the DTE. 8) Compatibility problem with Penril modem: When the modem was connecting with the Penril modem, the handshaking would fail during the phase 2 of V.34 hand shaking procedure. 9) Wrong help message: If the multi-language feature of Germany version was enabled (S63=1), a wrong message "&N61 V.34b 31200" would be shown on screen with "AT&$" command. 10) Wrong indication of AA LED: The indication of AA LED was incorrect when the modem was set by the following command sequence: . AT&FS1=1&WZ : . AT&FS0=1 : AA LED lights on and indicates auto-answer mode. . ATZ : AA LED lights on but the S-register S0 is equal to 0. 11) Failed to respond to the ATX0D command: When "ATX0D;" command was entered, modem would hang and fail to accept the AT command. 12) Could not detect incoming ring signal: After executing "ATDxxxx;" and then "ATH" command, the modem would not be able to recognize the incoming ring signal. 13) Failed to dial with the synchronous V.25bis command: When the modem started dialing with the V.25bis "CRN" command, the dialing digits did not go through and then modem went on hook. 14) Failed to perform the analog loopback with self-test (AT&T8) in the non-error control mode (AT&K0). 2. Fixed fax bugs: ------------------ 1) Wrong result with the "ATI2" command after FAX send/receive: After a fax connection, with the "ATI2" command, the modem reported the last baud rate with the wrong value of "28800". 2) Improved reliability of V.21 HDLC receiving. 3) The compatibility problem with Panasonic fax machine: When the FAX machine did not send the ANSWER tone, the modem would disconnect the outgoing call instead of sending out the fax. 4) The problem of the Postscript FAX receiving/printing fixed. Postscript printing margin can be configured by paper type. 3. Fixed voice bugs: -------------------- Incorrect RI lead indicator of RS232: When modem went off-hook to answer the incoming call and play the voice greeting message in the voice mode, RI lead (pin 22 of RS232) kept high. Even aborting or terminating the voice playing, RI was still high. 4. New modem features: ---------------------- 1) Support Germany message display for commands: . ATI2 : report link diagnostic status . AT&Vn : view current active or user profile settings . AT#B3 : measure the ring cadence . ATDL : dial the last-dialed number 2) When the DTE speed was set to 19200, the highest connection rate would be limited to 19200 bps. 5. New fax features: --------------------- A fax protocol capture utility was implemented for debugging the FAX compatibility problem. This feature is not available for the FAX direct printing mode. S76: bit0 = 1 FAX response capture enabled bit1 = 1 FAX command capture enabled bit2 = 1 V.21 HDLC Tx/Rx capture enabled Use "AT+FZX?" command to show the captured log on terminal. 6. New voice features: ----------------------- 1) Add three sampling rate : 7200, 8000, 11025 bps 2) Add three digital compression algorithm : DVI ADPCM, A-law PCM, Mu-law PCM. 3) The command "AT+VSM=?" will show you how to use these new features.

Known bugs of v1.12: ("very sorry, very sorry - it's not perfect yet") These bugs were recognized on March 14th, 1996: ------------------------------------------------------------------------ 1) The modem has problem with 11-bit character length. 2) Remote configure (*Wab) fails over V.22bis connection. 3) Security function (*G3) fails and causes modem reset. 4) Connect with V.22bis (2400 bps) with MNP5 data compression will transfer no data - please disable MNP5 feature with ATS38.5=1 ----------------------------------------------------------------------------- Release Note on Elite 2864 Version 1.11 Jan. 26, 1996 1. Improved the V.34 performance. --------------------------------- 2. Fixed modem bugs: -------------------- 1) The "carrier lost 1" problem: When the modem is connected to a Rockwell chipset based modem on some long distance calls, the modem will drop the line immediately with disconnect reason shown "carrier lost 1". 2) Incorrect LED indication: The V34 LED does not turn on if "AT&N62" to "AT&N72" command is entered. The "V32b" LED will turn off if a V.32 connection is established with "AT&N4" command. 3) Can not connect on two wire leased line mode: If "AT&L1" command is entered, the modem will go on-hook and report "NO CARRIER" immediately after connection. 4) Wrong leased line operation: If "AT&L1" command is entered, modem will go to handshaking procedure immediately. 5) Incorrect response for numeric form result code (ATV0): If "AT&K0&N14V0" command is entered, modem reports connect message as "10" instead of "10" after connection. 6) Unable to use V.25bis command set. 7) Sometimes in data state, the modem does not disconnect when DTE drops the DTR signal. 8) Impoved the reliability of recognizing the dial tone, busy tone and ring signal in Italy. 3. Fixed fax bugs: ------------------ 1) Incorrect response: Modem reports "+FHNG:70" followed by "NO CARRIER" while the incoming call is a voice call. 2) Some compatibility problems of class 1 commands with Win95. now the modem responses to the AT+FCLASS=? inquiry with the string "0,1,2,2.0,6,8,Z" 4. Fixed voice bugs: -------------------- 1) Fix the problem of BUSY tone detection of Italy: In Italy, the modem does not recognize the busy tone in voice mode. After recording a message, the modem does not go on-hook and continue to record the busy signal. 2) Improved the VCON reliability. 5. Added new features: ---------------------- 1) Some new user friendly commands: ? or $ Basic command summary help. &? or &$ Extended AT& command summary help. *? or *$ Extended AT* command summary help. #? or #$ Extended AT# command summary help. +? or #$ Extended AT+ command summary help. S? or S$ Show complete register list Sxxx=? Show the function of Sxxx register. Sxxx=$ Show the function of Sxxx register. 2) Multi language support: Right now, only two languages are implemented. If the value of S63 equals 1, the summary help is displayed in German. If the value of S63 equals 0, or any value other than 1, the summary help is displayed in English. [Note] . Right now, not all the information pages are available in both languages. So the help display is 'a bit' mixed sometimes. But this will be filled up with the correct language as soon as possible. 3) Report "DATA or FAX" before showing connect message: If bit7 of register S57 is set (default is reset), an additional connect message will be displayed on the screen. The additional message is "DATA" or "FAX" for data or fax connection respectively. For example, AT+FCLASS=1 AT+FAA=1 example 1: DATA CONNECT 115200/V34 28800/V42b/SREJ example 2: FAX CONNECT 4) The capability of fax receiving in class 6 is configurable. ============================================================================= Release Note on Elite 2864 Version 1.10 Dec. 22, 1995 1. Fixed modem bugs: -------------------- 1) Improper remote configuration: The local modem can not read or write the remote modem's profile on connection. (Note: Remote configuration is not inter-operable between an Elite 2864 and a U-1496 series modem. The Elite 2864 has more S-registers and some S-registers have different meaning.) 2) AT&T6 (initiate remote digital loopback) does not work. 3) Fail to recognize the dial tone of some PABXs: During dialing, the modem reports "NO DIALTONE" when the dial tone is not a continuous signal (with ON/OFF cadence). 4) Incorrect LED indication of dialing, handshaking and retrain: The V32b LED does not flash on and off for 1/2 second each to indicate that the modem is dialing. Neither do the V34 and V32b LEDs flash on and off for 1/2 second each to indicate that the modem is in handshaking or retrain. 5) "ATM3" does not work: With the "ATM3" command, the dialing tone is still heard from speaker. 6) Type 1 security function does not work (the *G1 and *G2 commands). 7) Does not support up to 50 passwords in security function: For example, in *G4 setting, the modem is not able to detect any password at location from #10 to #49. 8) Unable to recognize ring signal on some bad local loop lines. 9) Incorrect repeat dialing function: When bit0 of S38 is set, the modem will not dial the same number again while the modem reports "BUSY" after dialing. 10) Incorrect cyclic dialing: When bit3 of S44 is set, the modem will not dial the second number while the modem reports "BUSY" after dialing. 2. Fixed fax bug: ----------------- 1) Incorrect LED indicator: When "AT+FCLASS=6" command is entered, the V34 LED turns off in multi-auto mode (AT&N0). 3. Fixed voice bug: ------------------- 1) Sometimes the modem hangs after issuing to finish playing voice. 4. Add new features: -------------------- 1) Set the dial back timer S64 for security call back function: (default=0, in seconds) With level 2 security, the answer modem will disconnect the line if the password has been found in its pre-stored acceptable list. The answer modem will dial back the phone number corresponding to the dial-in password, when the dial back timer (containded in S64) is reached. If the content of S64 violates the PTT regulation, the dial back timer will be automatically set to the value defined in PTT regulation. S64 can be used to control the dial-back waiting time to avoid dialing back too quickly that the calling modem's line is still busy. ============================================================================= Release Note on Elite 2864 Version 1.09 Dec. 8, 1995 1. Fixed modem bugs: -------------------- 1) Fail to recognize the Italian dial tone. 2) Failure in dial tone monitoring: When "ATH1" command is entered, the modem goes offhook but there is no dial tone coming from the modem's internal speaker. 3) Incorrect response for numeric form result code (ATV0): For example, when "AT+FCLASS?" command is entered, modem responds with "00" instead of "00" in numeric form. 4) Problem on forcing V.22bis retrain: In V.22bis escape state, when "ATO1" command is entered to force the modem to request a retrain, the connect message shows "V.32 9600T". And sometimes the retrain fails. 2. Fixed fax bugs: ------------------ 1) Problem on fax reception: Sometimes the top portion (the first half inch) of the received page is chopped off when the receiving speed is 14400bps. 2) The AT+FZF=1 setting is not saved with AT&W command. 3. Add new fax feature: ----------------------- 1) The local ID string (AT+FLI=) can be saved to EEPROM with AT&W command. 4. Add new voice features: -------------------------- 1) Some programmers need the feature to enable the speaker when recording from telephone line. In this version, we let users use VLS=18 (16+2, speaker and Telco Line) to enable the speaker. 2) Some programmers also report that the transmit level of Tone (+VTS) and Voice (+VTX) are different. In this version, we let users set the transmit gain separately, AT+VGT for Voice and AT+VGN for Tone. The default value of AT+VGT is 128. The default value of AT+VGN is 60. 3) In this version, users can use s60 bit 4 to disable the Telco line playback AGC. 5. Important notes for voice programmers: ---------------------------------------- From version 1.07, the Near Echo Cancellation is disabled as the default setting, this decreases the sensitivity and reliablity of DTMF detection when playing voice message. Set the s60 bit 7 will enable the NEC ! ============================================================================= Release Note on Elite 2864 Version 1.08 Nov 27, 1995 1.

Note: -------- 1) Change the default value of ring volume control from "N5" to "N3". ----------------------------------------------------------------------------- Release Note on Elite 2864 Version 1.07 Nov 16, 1995 1. Improved V.34 performance. ----------------------------- 2. Fixed modem bugs: -------------------- 1) Wrong response to ATDT;H command: the modem doesn't hang-up after dialing the phone number. 2) Wrong response to AT&FX7S6=5&W1Z1 command: viewing the setting by AT&V, the modem responds with the default setting of X5 and S6=2, in stead of X7 and S6=5. 3) Wrong AT command entered in escaped state will cause hang: if any wrong AT command is issued in escaped state, the modem will not respond to any futher AT commands. Modem should be powered off and on to reset. 4) Modem hangs: when the modem is ringing and the RS-232 cable is pluged in, then the modem will not respond to any futher AT commands. Modem should be powered off and on to reset. 5) Unable to send data calling tone for V.32b/V.22b/ZyX19200/ZyX16800 modes. 6) Connection problem when calling tone enabled: When the calling tone is enabled (AT&F&N0S48.2=1), the connection made with U-1496 plus models can only reach 16800 bps (the 19200 bps connection is not possible). 7) Wrong LED display: When the modem is connected with ZyX 19200 or 16800 bps, the LED V34 and V32b are ON. That is OK. But when you enter "+++" escape command and then "AT" command, the V32b LED goes OFF. 8) The S14 register does not contain the exact value of the command AT*M0 and AT*M1. For example, with command ATZ1*M1&V, the display shows the value of S14 bit 0 is 0; with command ATZ1S14.0=1&V, the display shows *M0. 9) The supervisory password entry can take only 7 characters: Try setting for example password #8 but type more than 8 characters and you will get "ERROR". 10) Problem of connecting to host with 7 data bits, even parity and 1 stop bit protocol: There is a problem when you try to connect to the "telebanking" service, where 7E1 protocol is used. What is supposed to happen is that you enter the user ID followered by , and then the host prompts you for the password. The bug is as soon as a numeric digit is entered, it behaves like a has been entered as well, and the host prompts for the user-ID again. After 3 incorrect attempts, you are automatically logged out. 11) On the password table, for example setting *G4, the modem is not able to detect any password at location #10 to #49. 3. Fixed fax bugs: ------------------ 1) In direct fax printing mode (AT+FCLASS=Z and AT+FZF=0), when a data call comes, the modem serial port will hang. (Can't switch from parallel port to serial port.) 2) V34 and V32b LED doesn't goes off in FAX mode. 3) CD on immediately after dialing in FAX Class 1 mode. 4) In fax DRAM retrieing mode, the RS-232 RI signal is not sent to DTE when "RING" string is sent to DTE. 4. New fax printing feature: ----------------------------- 1) Support Postscript Printer. 2) Support HP DJ500 series Inkjet Printer. 3) Support Serial Port Fax Printing. 4) Speedup PCL Printing. New FAX feature Setting Registers: S72: Set Printer Type $0 : HP laser jet II series PCL Printer HP Deskjet 500 Series $1 : HP laser jet III series PCL Printer $2 : POSTSCRIPT Level I Printer S73: Flag for fax printing bit0: Fax Printing Port : 0 = Parallel Port (default) : 1 = Serial Port bit1: Fast PCL Printing. : 0 = On (default) : 1 = Off bit2: PCL Print resolution : 0 = 300dpi (default) : 1 = 150dpi bit3: Resize Flag : 0 = do not resize : 1 = resize (default) bit4-6: Paper Size : 000 - LETTER(default) : 001 - LEGAL : 010 - A4 AT+FZT=xxx : Set Fax Speed in Direct Fax Printing Mode. +----------+-----------+-------------------+ | | | Scanline Time | |FZT Value | Fax Speed | Hi-Res Low-Res | +----------+-----------+---------+---------+ | 0- 15 | 14400 | 0ms | 0ms | | 15- 31 | 14400 | 5ms | 10ms | | 32- 47 | 14400 | 10ms | 20ms | | 48- 63 | 14400 | 20ms | 40ms | | 64- 95 | 14400 | 40ms | 40ms | | 96-127 | 9600 | 40ms | 40ms | | 128-195 | 4800 | 40ms | 40ms | | 196-255 | 2400 | 40ms | 40ms | +----------+-----------+---------+---------+ AT+FZT=? : View current setting of Fax Speed in Direct Fax Printing Mode. Usage of Direct Fax Printing via serial port: --------------------------------------------- 1) Connect modem to PC via the RS-232 serial port. 2) Use a terminal Software to communicate with Modem 3) Set Baudrate = Serial Printer's Maximum Baudrate. (For example, if the max. baudrate of your serial printer is 38400, please use 38400 for terminal software) 4) Setup S72. (0,1 for PCL, 2 for Postscript printer) 5) Set AT+FZF = 0. (Direct Fax Printing) 6) Set AT+FZT Value. (This value relies on the printer speed, baud rate of serial port and printing language (Postscript is faster than PCL). The principle on deciding this value is: PRINTING MUST BE FASTER THAN FAX RECEVING!!! Because in AT+FZF=0 mode, received data is sent to printer directly. Therefore, fax printing speed must be faster than fax receving speed. Otherwise the internal buffer will overflow and some scanlines must be discarded. First, you can try AT+FZT=150. If it is OK, then you can try 100, 64, 48, 32, 16 and 0 to get the optimal speed. This value depends on your printer's printing speed. 7) Setup S73. (Configure fax printing options, bit 0 must be 1 for serial printing) 8) If auto-receving is needed, please set S0=1. 9) Set AT+FCLASS=Z. (Enable Fax Printing) 10) Use AT&WZ to store current setting to profile 0. (Store All S-Regs and Baudrate Settings in EEPROM) 11) Connect modem to printer Via the RS-232 serial port. Note: 1) In Serial Printing Mode, only DTR flow control is supported. Please setup your printer to accept DTR flow control. 2) Because the modem's serial port type is of DCE type, the printer's serial port type must be of DTE type. If the printer's serial port is also of DCE type, a NULL MODEM adapter (or cable) is needed. <1> Modem in normal operation : RS-232 Cable Modem(DCE) <------------> PC(DTE) <2> Modem is connected to a DTE Serial Printer: RS-232 Cable Modem(DCE) <------------> Printer(DTE) <3> Modem is connected to a DCE Serial Printer: RS-232 Cable Modem(DCE) <--> Adapter <------------> Printer(DCE) 3) In order to achieve maximum throughput, please use the maximum baud rate your printer permits. 5. Fixed voice bugs: -------------------- 1). Playing problem with 3-Bit ADPCM data. 2). Increase the reliablity of VCON detection. 3). Enhance the voice quality of local telephone phone set. 6. Add new voice features: -------------------------- 1). When first playing through telephone line, the default setting is disable the Near Echo Cancellation. The users can enable this feature by setting the bit 7 of s60 to 1. ----------------------------------------------------------------------------- Release Note on Elite 2864 Version 1.06 Sep 13, 1995 1. Improved FAX V.17 receiving performance. 2. Improved FAX V.21 sensitivity. 3. Improved FAX printing quality. 4. New FAX feature: (1) Function of s73 bit3: Set S-register s73 bit 3 to 1 (ATS73.3=1) will enable direct FAX printing application to print longer FAX pages to LETTER size paper. For off-line DRAM receiving and printing application, if s73 bit 3 is set to 1 the printing driver will automatically and dynamically select a zooming factor and print the FAX pages to fit the selected paper size. The zooming factor depends on the page length of the received FAX. The default setting of this feature is on (s73 bit 3 is set to 1). (2) AT+FZL? command: Show FAX receiving log For example, No. Remote FAX ID Speed Pages Size Status Hardcopy Retrieved === ==================== ====== === ===== ====== ======== ========= 1 886-35-782439 * 9600 3 110k OK YES 2 1-714-693-8811 14400 2 90k OK Free DRAM Size: XXX Where "No" ------------- Session log number "Remote FAX ID" -- Sending FAX machine indentifier (TSI) "Speed" ---------- Fax receiving speed and resolution "*" - fine resolution "Pages" ---------- Number of pages "Size" ----------- Log size (number of bytes) "Status" --------- Receivig result , "OK" or error code "Hardcopy" ------- FAX printing status "Retrieved" ------ Retrieved by FAX software if marked "YES" (3) AT+FZP=nn command: Print the received FAX by specifying the session log number "nn". 5. Fixed bugs: * FAX CNG tone transmitting: Sometimes it works but sometimes it doesn't work. * Data calling tone: When the data calling tone is enabled and a connection is made to another modem, the remote modem will show the wrong connect message like "CONNECT 115200/V.22 1200/NONE", but acturally the connection is not successful. * AT*Pn: AT*Pn can not be saved to profile. For example, originally at&f&v shows *P11. When at*p9&w0z&v is issued, the modem still shows *P11 instead of *P9. 6. Improved performance on FRN (fast rate renegociation). ------------------------------------------------------------------------------ Release Note on Elite 2864 Version 1.05 Aug 14, 1995 Note: Version 1.03 and 1.04 are not formally released, their relase notes are accumulated here. 1.

It is corrected to 2400/ARQ/V.22b/V42b. * AT command response error: the response of AT&N after AT& was ERROR. * Wrong display of V34 and V32b LEDs. For example, when the modem connects in ZyX mode, both the V.34 and V.32 LED come on but when there is a retrain the V32bis LED goes off. 3. When the DTE speed is set to 9600, the highest connection rate will be limited to 9600 bps. 4. The default connection mode for multi-auto mode will be V.34 28800 on leased line operation. 5. Improved performance on FRN (fast rate renegociation). ------------------------------------------------------------------------------ Release Note on Elite 2864 Version 1.02 Aug 01, 1995 1. Fixed bugs: * ATS0: If you give ATS0=3 or other values, very often the modem answers on the first ring. * ATS1: The S1 register does not collect the number of rings received. * ATS38: The command S38=32 (or S38.5=1) that disables MNP5 doesn't work. * MNP hang: After retraining and connecting on MNP mode, the modem will "hang" and can not accept any command. * V32bis hang: When the modem is connected in V32bis, sometimes, the connection can not be dropped by lower DTR. The DTR LED is always ON and the modem has to be turned off. * The sending and reception of break signal does not work correctly for error control mode. * The response of ati2 command (following at&z? command) is incorrect. * When the modem is connected in V.22bis, the SQ LED will flash or always OFF. * When ATQ2 is issued, the modem still responds to EDR and gives RING message. 2. ATI2 will display both transmission and receiving connection rate. 3. Remove two from at&v response. 4. Add AT&N12 to on-line help menu. ------------------------------------------------------------------------------ Release Note on Elite 2864 Version 1.01 July 23, 1995 1.
