INTRODUCTION
Multi-Com is a specialized full duplex data communications
program, that will transfer files between two PCs. Multi-Com
uses Asynchronous Data Link Control (ADLC) communication
protocol. ADLC is the heart of Multi-Com and is the single
factor that permits concurrent file transfers. Concurrent
file transfer is the ability to upload and download files
at the same time.
Your Multi-Com program has a unique sign on ID and PASSWORD.
You must remember your ID and PASSWORD. If lost, it can not be
replaced. The ID and PASSWORD are used for automatically logging
on to remote PCs that use the Multi-Com FTS host software. You
may see other references to the MC-FTS within this manual. The
MC-FTS is the "Multi-Com File Transfer System" program. The
MC-FTS program is used for unattended host operation with
Multi-Com. Multi-Com users can call into the MC-FTS to download
and upload files and messages. An operator is not needed to run
MC-FTS.
The first time Multi-Com is loaded, it should be configured for
your particular system. This includes setting the default
communication port, baud rate, download path, upload path and
system security. To do this, see the configuration section
starting on page 3-1.
This document file assumes you have a basic understanding of DOS.
See your DOS manual if you need more information about DOS and
it's commands.
Note: The Multi-Com program must be running in both PCs. This
program will not transfer files with another system unless
that system supports ADLC protocol.
Page: 1-1
INTRODUCTION...
The program diskette contains the following files:
RUN.BAT Batch File To Begin Multi-Com
MC105.EXE Multi-Com Program Version 1.05
MC_CNFG.DAT Configuration Data File
MC_DIAL.DAT Dialing Directory Data File
MC105.DOC This Document File
Page: 1-2
HARDWARE REQUIREMENTS
Multi-Com will run on an IBM-PC, IBM-XT, IBM-PC Portable, IBM-AT,
and IBM Personal System/2 series machines. It will also run on
all 100% IBM compatible machines. Downloading or uploading from a
diskette drive is supported, but can be slow if only one or two
files are being transferred. A fixed disk or VDISK is
recommended to increase overall performance.
Hardware: - 256k Memory Minimum
- 1 Disk Drive Minimum (VDISK or Fixed Disk Recommended)
- Color or Monochrome Adapter
- Color or Monochrome Display
- Asynchronous Communication Adapter and External Modem
or
- Internal Modem
Note: Multi-Com will not operate on a PCjr or on any machine that
does not have DMA and COM adapter hardware interrupt support.
Page: 1-3
SOFTWARE REQUIREMENTS
Multi-Com will run under DOS version 2.1 through 3.3 or TopView
1.0 through 1.1. If running under TopView, the screen must not be
defined as mode 3 or 7. All other modes will work fine. You
should unload all memory resident programs before starting
Multi-Com.
Software: - IBM or MS DOS Version 2.1 Through 3.3
- TopView 1.0 or 1.1 (Not Screen Mode 3 or 7)
- CONFIG.SYS file Containing The ANSI.SYS Device Driver
Page: 1-4
DOS SETUP
Multi-Com uses ANSI control codes to control your screen. In
order to properly view certain files, you must include the
ANSI.SYS device driver in your system configuration. To do this,
include the DEVICE=ANSI.SYS line in the DOS CONFIG.SYS file. If
you do not use a CONFIG.SYS file, one must be created. See your
DOS manual for more help with CONFIG.SYS and the ANSI.SYS device
driver.
Because Multi-Com can transfer multiple files at the same time,
multiple files will be opened at the same time. This can cause
problems for DOS if you do not set aside some memory for managing
all of the open files. To do this, put a FILES= command in the
CONFIG.SYS file. The maximum amount of open files with Multi-Com
will be 20. This is in addition to the files DOS will have open.
A FILES=32 in the CONFIG.SYS should provide satisfactory
operation with most system configurations. The BUFFERS= command
should contain the same value as the FILES= command.
A VDISK should also be configured if you have more than 256k of
RAM. All memory in excess of 256k can be assigned to the VDISK.
See your DOS manual for information about installing a VDISK.
The need for a VDISK will be greater for systems that do not
have a fixed disk. Diskette based systems will benefit more
from the VDISK.
CONFIG.SYS: - DEVICE=ANSI.SYS
- FILES=32
- BUFFERS=32
- DEVICE=VDISK.SYS (see your DOS manual for parameters)
Page: 1-5
GETTING STARTED
Before you load Multi-Com you must have the following files in
your default directory. It may be easier for you to create a
sub-directory with the DOS MD command and place the four
Multi-Com files in the newly created directory.
RUN.BAT Batch File To Start Multi-Com
MC105.EXE Program File Version 1.05
MC_CNFG.DAT Configuration Data File
MC_DIAL.DAT Dialing Directory Data File
The following is an example of the recommended DOS tree structure:
(root directory)
│ │
(com program sub-directory) (your other sub-directories)
│ │ │
│ │ └──────────────────────────┐
│ └──────────────────┐ │
(com program 1) (com program 2) (MC) <--The Multi-Com sub-directory)
││
┌─────┘└────┐
│ │
(DOWN) (UP)
Sub-Directory
-------------
MC Contains Base Files: MC105.EXE MC_CNFG.DAT,
MC_DIAL.DAT and RUN.BAT
MC\DOWN Will Contain Files That You Receive From
The Other Machine
MC\UP Contains Files That You Will Send To The
Other Machine
Note: The Multi-Com sub-directory MC can be anywhere on your disk.
Page: 2-1
PROGRAM LOAD
To begin Multi-Com enter RUN on the DOS command line. RUN is a
batch file used to start Multi-Com. RUN will check that needed
files are in the default directory. After the program loads, the
logo screen will appear on the default monitor. Multi-Com will
now wait for you to enter your personal ID and PASSWORD. Your
personal ID is used for automatically logging on to remote PCs
that use the Multi-Com FTS host software.
The following is a portion of the Multi-Com log screen. When you
see this screen, enter your ID and PASSWORD.

ID Word:_
Password:
──────────────────────────────────────────────────────────────────────
Version x.xx
After the correct ID and PASSWORD are entered, your use license,
name and address will replace your ID and password. The MAIN
MENU will be shown on line 24 and 25 with the DialingDirectory
option highlighted.
Page: 2-2
MENU SELECTION
All Multi-Com menus have the same format. Line 24 contains the
command selections and line 25 contains the alternate key and a
help message for that command. Most commands may be selected one
of three ways:
1) Enter the first letter of the command.
2) Move the command window with the left and right
arrow keys and press the ENTER key (NumLock must
be off).
3) Press the alternate key for that command (optionally
shown between the brackets on line 25).
Note: The Esc key will always select the LAST menu item. The last
menu item is always a command that will exit the current
menu and return control to the previous menu or screen.
Page: 2-3
MAIN MENU
TERMINAL Configuration DialingDirectory Exit
[ Com:1 Baud:1200 ] Begin Multi-Com terminal program
The main Multi-Com menu has four commands from which to choose.
The command may be selected by pressing the first letter of the
command or by moving to the command with the left/right arrow
keys and pressing ENTER. While the MAIN MENU is displayed, the
communications line is not enabled. The modem can not send or
receive information.
Remember: The left and right arrow keys (cursor movement keys)
will only work when Numeric Lock is turned off.
Page: 2-4
MAIN MENU...
TERMINAL COMMAND
TERMINAL Configuration DialingDirectory Exit
[ Com:1 Baud:1200 ] Begin Multi-Com terminal program
The first main menu command is called TERMINAL. TERMINAL will
take you directly to the Multi-Com communications screen.
Multi-Com will enable the communication line by raising the DTR
(Data Terminal Ready) signal to the modem. Multi-Com will then
check to make sure the line is enable by looking at the DSR (Data
Set Ready) signal from the modem. See page 5-1 for more
information about the TERMINAL operation.
CONFIGURATION COMMAND
Terminal CONFIGURATION DialingDirectory Exit
[ Com:1 Baud:1200 ] Display/Alter initial program settings
The second command is CONFIGURATION. This command is used to set
the default com port, baud rate, upload/download paths and to
enable or disable RDOS security. The com port and baud rate set
here are used as initial settings when the program is loaded.
They are overridden when you make a connection using the
DialingDirectory. See page 3-1 for more information about this
command.
Page: 2-5
MAIN MENU...
DIALING DIRECTORY COMMAND
Terminal Configuration DIALINGDIRECTORY Exit
[ Com:1 Baud:1200 ] Initiate a call
The third command is called DIALING DIRECTORY. This command will
take you to the Multi-Com auto-dialer. The auto-dialer is used to
program "intelligent" or "smart" modems. The directory holds 20
entries. Each entry has its own system Name, Number, ComPort,
Echo local/remote switch and DialCommand. When dialing a remote
machine with the DialingDirectory, the com port and baud rate are
taken from the individual directory entry. This overrides the
initial com port and baud rate set with the "Configuration"
command. See page 4-1 for more information about this command.
EXIT COMMAND
Terminal Configuration DialingDirectory EXIT
[ Com:1 Baud:1200 ] End this Multi-Com session
The last command, EXIT, will end Multi-Com and return control to
DOS or TopView. If the communication line is disabled, Multi-Com
will terminate immediately. If it is enabled, another menu will
come up. This menu will ask if you want to disable the line or
leave it enabled when Multi-Com terminates. Leaving it enabled
will keep DTR active. Choosing to disable it will make DTR
inactive thus causing the modem to hang up.
Page: 2-6
CONFIGURATION MENU
Terminal CONFIGURATION DialingDirectory Exit
[ Com:1 Baud:1200 ] Display/Alter initial program settings
BAUD ComPort DownloadPath UploadPath Protocol Secure Return
[ Com:1 Baud:1200 ] Select next baud rate
The configuration menu is selected from the MAIN menu by pressing
the letter "C". It has seven commands. The Baud and ComPort
settings are only used if you do NOT use the DialingDirectory to
initiate a call. The individual DialingDirectory entries for Baud
and ComPort will override these initial settings.
Page: 3-1
CONFIGURATION MENU...
BAUD COMMAND
BAUD ComPort DownloadPath UploadPath Protocol Secure Return
[ Com:1 Baud:1200 ] Select next baud rate
The BAUD command is used to set the communication port baud rate.
To change the baud rate, move the command window using the left
or right arrow keys to highlight the word BAUD. Press the ENTER
key to select the next baud rate. The baud rate is displayed
between the brackets on line 25. Available baud rates are 300,
1200, 2400, 4800 and 9600 baud. An alternate method for
selecting the next baud rate is to press the "B" key.
COMPORT COMMAND
Baud COMPORT DownloadPath UploadPath Protocol Secure Return
[ Com:1 Baud:1200 ] Select next com port
The COMPORT command is used to set the default communication
port. To change the com port, move the command window using the
left or right arrow keys to highlight the word COMPORT. Press the
ENTER key to select the next com port. The current com port is
displayed between the brackets on line 25. Available com ports
are 1, 2, 3 and 4. An alternate method to select the next com
port is to press the "C" key.
Note: When you use the DialingDirectory to initiate a call,
Multi-Com will NOT use the the COM PORT or BAUD rate from
the Configuration menu, but rather the COM PORT and BAUD
rate from the individual DialingDirectory entry.
Page: 3-2
CONFIGURATION MENU...
PATH COMMANDS
Baud ComPort DOWNLOADPATH UploadPath Protocol Secure Return
[ Com:1 Baud:1200 ] Set download path for files that you receive
Baud ComPort DownloadPath UPLOADPATH Protocol Secure Return
[ Com:1 Baud:1200 ] Set upload path for files that you send
The next two commands are used to set the UPLOAD and DOWNLOAD
paths. The DOWNLOAD path is where new files will be placed and
the UPLOAD path will contain files to be sent to the other
machine. These two paths should point to fixed disk or VDISK
sub-directories. They may also point to diskette drives. The two
paths may be the same. Blank paths are allowed. Due to the
nature of concurrent downloading, files that you receive will not
be contiguous. That is, they will not be made up of consecutive
disk sectors. To eliminate this "hashing of files", the DOWNLOAD
path should be a "temporary" area on your disk used only for
Multi-Com downloads. Then, after the Multi-Com session has
ended, move the newly downloaded files to a more permanent area
of your disk.
The following is a sample tree structure for the download and
upload paths:
(MC) <--The Multi-Com sub-directory)
┌─────┘└────┐
(DOWN) (UP)
Sub-Directory
-------------
MC............. Contains base files MC105.EXE , MC_CNFG.DAT,
MC_DIAL.DAT and RUN.BAT.
MC\DOWN........ Will contain files that you receive from the
other machine. Move these files to a different
area on your disk after the Multi-Com session has
ended.
MC\UP.......... Contains files that you will send to the other
machine.
Page: 3-3
CONFIGURATION MENU...
PROTOCOL COMMAND
Baud ComPort DownloadPath UploadPath PROTOCOL Secure Return
[ Com:1 Baud:1200 ] Select file transfer protocol
The PROTOCOL command is used to alter the file transfer protocol.
Version 1.05 of Multi-Com only supports ADLC protocol. ADLC is a
concurrent asynchronous file transfer protocol. ADLC, as
implemented in Multi-Com, will permit FULL DUPLEX transmission of
files between two machines over a single phone line, using a full
duplex modem such as a HAYES smart modem or compatible.
Concurrent downloading and uploading are supported. Multi-Com
uses 7 of the 8 ADLC links in single mode only. Link #1, the
console link, is a dual mode link. All links will operate in dual
mode only when the terminal is in local or remote loop-back mode.
Dual mode operation is both transmitting and receiving over 1 of
the 8 concurrent links. Single mode operation is either
transmitting or receiving over 1 of the 8 concurrent links. All 8
links will run at the same time regardless of the individual link
mode.
Link # Mode Use
------ ---- ---
1 TR Dual Mode Link Used For Console To Console
Communications (Both Transmit And Receive)
2 T or R Single Mode Link Used For Disk To Device
Transmissions (Printer or Plotter)
3 T or R Single Mode Link For Disk to Disk Transmissions
4 T or R Single Mode Link For Disk to Disk Transmissions
5 T or R Single Mode Link For Disk to Disk Transmissions
6 T or R Single Mode Link For Disk to Disk Transmissions
7 T or R Single Mode Link For Disk to Disk Transmissions

DIALING DIRECTORY MENU...
DIAL COMMAND...
DIAL will build two command lines and send them to your modem.
Your modem does the actual dialing. The commands that are sent
to your modem are made up of different Multi-Com parameters. The
parameters in the first modem command are all taken from the
DialingDirectory menu. They are PREFIX, INIT and TERMCHAR. They
are used to reset or initialize your modem.
The format is:
3 TERMCHAR's + PREFIX + INIT + TERMCHAR
If TERMCHAR was a carriage return (ASCII 13), PREFIX was AT and
INIT was Z , then the modem would be sent:
cr cr cr ATZ cr
The second command sent to the modem is the actual modem dial
command. This includes the DIALCOMMAND and NUMBER from the
individual directory entry.
The format is:
3 TERMCHAR's + PREFIX + DIALCOMMAND + NUMBER + TERMCHAR
If TERMCHAR was a carriage return (ASCII 13), PREFIX was AT ,
DIALCOMMAND was DT and the NUMBER was 276-3374 , then the
modem would be sent:
cr cr cr ATDT276-3374 cr

modem uses as it's command terminating character. For most
modems it would be an ASCII 13, which is a carriage return. If
your modem needs something other than that value, set it with
TermChar. The range is 1 to 255.
WAIT TIME COMMAND
Dial Edit Prefix Init TermChar WAITTIME SpaceConvert Return
Modem wait time between characters: [5]
The WAIT TIME command is used to control how fast characters are
sent to your modem. The default is 5. Lowering this number speeds
up commands to your modem. Increasing this number slows down
commands to your modem. If the DialingDirectory is not able to
auto-dial your modem, increase this number. The range is 1 to 9.
The WaitTime is calculated using the following two formulas:
Time between commands = 1.1 sec + ( .1 sec * WaitTime )
Time between characters = .006 sec * WaitTime
This gives a range of 1.2 to 2.0 seconds between commands and
.006 to .054 seconds between characters. Using the default of 5
yields a time of 1.6 seconds between commands and 30 milliseconds
between characters. Some HAYES compatible modems will require the
full WaitTime value of 9 before they will auto-dial.

DIALING DIRECTORY MENU...
SPACE CONVERT COMMAND
Dial Edit Prefix Init TermChar WaitTime SPACECONVERT Return
Character converted to a space: [$]
The SPACE CONVERT command is used to change the character Multi-Com
will convert to a space within a modem command. The default value
is the dollar sign ($) character. If the SpaceConvert character
is other than a $ , then the $ character becomes a delay value
equal to the WaitTime value in .050 second increments. The delay
occurs within a modem command.
If the SpaceConvert character is a dollar sign [$]
then the command string [^n$DI$123-4567]
will be converted to [^n DI 123-4567]
before it is sent to the modem.
If the SpaceConvert character is an exclamation point [!] (or
anything but a dollar sign [$]:
then the command string [^n$DI!123-4567]
will be converted to [^n(.05sec*WaitTime)DI 123-4567]
before it is sent to the modem.
The need for the $ delay will vary depending on your modem. It
will NOT be needed for HAYES and HAYES compatible modems. Some
modems which support two command sets may need an extra delay
within the modem command.

KEYBOARD USE
The keyboard has two modes of operation. They are TERMINAL mode
and COMMAND mode. While in TERMINAL mode, all characters typed
will be sent to the REMOTE PC. In COMMAND mode, the characters
you type are interpreted as an internal command. To switch
between COMMAND and TERMINAL mode, hold down the CONTROL key and
press the ENTER key. CONTROL-ENTER can be used at any time to
toggle between COMMAND and TERMINAL mode.
The following pages will describe various keys and their meaning.
The descriptions apply when Multi-Con is in TERMINAL mode. To
display COMMAND menu #1, press the Esc key. Pressing the Esc key
a second time will display COMMAND menu #2. Pressing Esc a third

TERMINAL OPERATION...
F10 "MESSAGE PENDING" KEY
When the keyboard is in TERMINAL mode, you may communicate with
the other machine's operator by typing messages to him or her
with your keyboard. When MC-BLOCK mode is turned OFF, this is not
a problem because the other person can see each character as you
type. When MC-BLOCK mode is ON the other person has no way of
knowing when you are typing. As you type, the characters are
placed in a holding buffer until you press your ENTER key. After
you press ENTER, the line of information is then sent to the
other machine. This can be a confusing situation for both
involved. The problem can be kept to a minimum by the use of the
F10 key. The F10 key will send the message "MESSAGE PENDING" to
the other person and the message "PROCEED" to you. This lets the
other person know that you are in the process of typing and that
they should wait while you type. If you should receive the
message "Message Pending" while typing to another person, you
should wait until they are finished. Use the F10 key to let the
other person know you have started to type them a message. This
will eliminate the confusion of not knowing if someone is typing
a message, or waiting.

TERMINAL OPERATION...
INTERNAL COMMANDS
To pass information to the other machine's operator, your
keyboard must be in TERMINAL mode. To pass internal command
information to your Multi-Com program, your keyboard must be in
COMMAND mode. There are two ways to give internal commands. The
first is to place your keyboard in COMMAND mode by pressing
CONTROL-ENTER, then type the command and press ENTER. The second
is to press the ESC key to bring up the COMMAND menus. The
second way is a much easier way to pass commands to Multi-Com.
The COMMAND menus are in the same format as all other Multi-Com
menus. Selecting a command from the menu is the same as selecting
a command from any of the other Multi-Com menus.
The following pages will describe various internal commands. The
descriptions apply when the Multi-Con COMMAND menus are
displayed. To display COMMAND menu #1, press the Esc key.
Pressing the Esc key a second time will display COMMAND menu #2.
Pressing Esc a third time will re-display the STATUS line and
place Multi-Com in back TERMINAL mode.

Page: 5-11
TERMINAL OPERATION...
BLOCK COMMAND
BLOCK Ldos Rdos Upload Download Status Hold Quit Other Exit
[Ctrl-F1] Initialize Multi-Com Block Mode
The BLOCK command will initialize Multi-Com BLOCK mode operation.
Control-F1 is an alternate key for the BLOCK command. MC-BLOCK
mode must be initialized before files can be transferred with
another machine running Multi-Com. Once MC-BLOCK mode is active,
the STATUS line will change:
From:
──────────────────────────────────────────────────────────────────
<-> Character Terminal LE 0
To:
──────────────────────────────────────────────────────────────────
<=> MC-BLOCK Terminal LE 0
It is very important that a BLOCK command be issued at the start
of a Multi-Com to Multi-Com communication session. Without the
BLOCK command, Multi-Com will be in CHARACTER mode. Character
mode will allow you to type messages, but nothing else. MC-BLOCK
mode is required before you can transfer files. The BLOCK command
enables the ADLC protocol which is the FULL DUPLEX protocol used
for concurrent downloading and uploading.
During MC-BLOCK mode initialization, the two machines exchange
configuration information which is needed to support concurrent
operation. Line errors or noise during the initialization process
can cause it to fail. The message "REMOTE STATION HAS FAILED TO
RESPOND" indicates that the other machine is not running an ADLC
supported program, or line noise was too great to be overcome. If
MC-BLOCK mode fails to be set, retry the command.
Page: 5-12
TERMINAL OPERATION...
LDOS COMMAND
Block LDOS Rdos Upload Download Status Hold Quit Other Exit
LOCAL DOS, Type EXIT to return to Multi-Com
The LDOS command will put the Multi-Com program on hold and load a copy
of the COMMAND.COM DOS command processor. To exit LOCAL DOS and return to
Multi-Com type the DOS EXIT command. You must have 256k of memory (as
stated on page 1-3 ) for this command to work. If files are being
transfer, they will be temporarily halted before dropping to DOS. The
remote machine's terminal will go "BUSY" while you are using DOS. The
remote operator will not be able to access Multi-Com while you are in
LDOS. Care should be taken to return to the proper directory before
typing EXIT. Do not alter the screen mode while in DOS. Do not move
active files in or out of your UPLOAD or DOWNLOAD directory if links were
running before the LDOS command was given. Do not load other
communication programs while in LDOS. Do not load BASIC or BASICA. BASIC
will alter the communication port status and not permit Multi-Com to
resume halted file transfers.
RDOS COMMAND
Block Ldos RDOS Upload Download Status Hold Quit Other Exit
REMOTE DOS, Type EXIT to return to Multi-Com
The RDOS command is similar to the LDOS command. RDOS will give you
access to the remote machine's DOS through Multi-Com's CHARACTER TERMINAL
mode. Therefore, this command will be disabled while there are files
being transferred. The remote machine must have RDOS SECURITY disabled
before you will gain access DOS. Do not alter the standard input/standard
output devices while using RDOS. The remote machines STDIN and STDOUT are
redirected to the configured com port during RDOS operation. Do not load
BASIC or BASICA or any other program that may alter the communication
port or standard input/output device. Your best bet is to only use DOS
commands (DIR, CHKDSK, COPY, CD, MD, etc...) and then type EXIT to get
back out. After exiting RDOS you must issue the BLOCK command to get
Multi-Com from CHARACTER to MC-BLOCK mode. See page 5-12 for
information about the BLOCK command.

This is the command that will begin the process of sending a file
from your machine to the remote machine. When this command is
first selected all active file transfers will be temporarily
halted. You will then be prompted to enter the LOCAL INPUT
file name. The prompt for the LOCAL INPUT file will include
the configured upload path (see page 3-3 for
information about path configuration). Enter the name and
extension of the file. Do not include a path name. Next, you will
be prompted for the REMOTE OUTPUT file name. This field will have
as its default the name of the INPUT file. You may change this
name or press enter to accept the default. Multi-Com will
begin the file transfer using the lowest available link
address. Messages will display stating the success or
failure of the upload. See page 6-1 for message
meanings.

halted. You will then be prompted to enter the REMOTE INPUT file
name. Enter the name and extension of the file. Do not include a
path name. Next, you will be prompted for the LOCAL OUTPUT file
name. The prompt for the LOCAL OUTPUT file will include the
configured download path (see page 3-3 for information
about path configuration). This field will have as its default
the name of the INPUT file. You may change this name or press
enter to accept the default. Multi-Com will begin the file
transfer using the lowest available link address. Messages will
display stating the success or failure of the upload. See page

End this Multi-Com session and DO NOT disconnect line
The HOLD command is used to end the current Multi-Com session
and return to the MAIN menu. THE PHONE CONNECTION IS NOT ENDED.
Multi-Com uses the RS-232 DTR line to hang-up the phone. DTR
remains active and the modem does not hang-up. This command is
disabled if files are being transferred. It is useful if you
want to back out of TERMINAL operation and go to the MAIN menu
for some reason. If you should come back to the TERMINAL, you
must issue the BLOCK command to re-establish MC-BLOCK mode. See
page 5-12 for information about the BLOCK command.

The LOOP command will place the communication port in local wrap
mode. Local wrap mode is useful for becoming familiar with
Multi-Com in a stand alone environment. While in loop mode,
Multi-Com will think there is another machine connected to the
modem and all functions will be active. The letter L will
replace the < on line 25 to indicate that loop mode is active.
All file transfer links will operate in dual mode while loop mode
is active (see page 3-4 for information about dual mode).
Note: The LOOP command will not function on a PC-AT
serial/parallel card.
DROP COMMAND

TERMINAL MESSAGES...
MESSAGES...
[ All MC Links Are In Use ]
The DOWNLOAD or UPLOAD request can not be completed because there
are no links available for the transfer. This is because all
links are currently in use or the MC-FTS reduced the number of
available links. Multi-Com has a maximum of eight transfer links.
Link #1 is always used for console-to-console communications.
Link #2 is only used when a file is transferred from disk to a
printer. Link #3 to link #8 are used for disk-to-disk transfers.
If you had 6 disk-to-disk file transfers running and tried to
start the seventh, this message would be posted because the
seventh disk-to-disk transfer can not use link #2.
[ BLOCK MODE Is Active ]
The BLOCK command has successfully enabled Multi-Com BLOCK MODE.
The terminal has switched from CHARACTER TERMINAL mode to
MC-BLOCK mode and the ADLC protocol is now in control of the
communication line. Users with external modems will see the two
machines exchanging ADLC READY commands in the modem lights.

Multi-Com is not a standard communication program. Do not become
discouraged during your learning period. The idea of transmitting
a file from one machine to another over phone lines can be difficult
to understand. Understanding concurrent file transfers and multiple
file links and command mode and terminal mode and LDOS and RDOS and
well, you get the idea....please be patient and Multi-Com will
become a welcome addition to the communication software that you are
presently using.
