- MacPPP Revision History:
-
- 10/28/93
- 2.0.1 Release
-
- Fixes:
- -code to check for "AT" in modem init string was broken (oops).
- It now sends the string when the "AT" is present.
- -Think C 6.0.1 was having problems evaluating a particular
- inline asm construct (a bug in Think C). The offending line
- was modified so that it now compiles without errors.
- -PPP was not looping back IP packets addressed to itself. This
- is now done correctly.
-
- 10/22/93
- 2.0 Release
-
- Fixes:
- -Check for InitWindows was wrong which caused problems when MacPPP
- was started at init time or by certain applications.
- -Writes were done synchronously when dialing/connecting. This seemed
- to cause problems on certain machines. All writes are now async.
- A timeout was added for the writes.
- -Logic in control panel was goofy when adding new "servers".
- Moved "New" and "Delete" buttons to the main control panel dialog.
- -Code would not compile with type checking enabled. Cleaned it
- up so that it now compiles.
- -After a link timeout, control panel didn't update link status.
- -bug which could cause problems with > 1 active TCP sessions
- with VJ header compression enabled.
-
- Features:
- -Added support for DTR (InsideMacspeak, RTS in real world) flow
- control. This helps prevent hardware overruns on certain Macs
- (PowerBook 180's for sure) and with virtual mem. enabled. Also helps
- prevent software overruns on the slow Macs when running at high
- speeds. Thanks to Amanda Walker for the tip.
- -Added Deferred Task Manager support. Prevents losing timer/VBL
- interrupts when running at high speeds (transmitting in particular).
- -Added ShutDown Manager support. Will now hangup modem on restart
- or shutdown.
- -Now sends a Teminate Request before disconnecting. It should
- also now behave correctly when a Terminate Request is received.
-
-
- 7/19/93
- 1.1.3 Release
-
- Fixes:
- -Fixed bug introduced in the 1.1.1 so that PPP would work
- with Serial Drivers with names greater than 15 bytes
- (increased driver name arrays from 16 to 128 bytes).
-
- 7/9/93
- 1.1.2 Release
-
- Fixes:
- -Added "Hard Close" and "Soft Close" to get around MacTCP opening
- the link after extended idle periods. Clicking "Hard Close"
- will prevent MacTCP from re-opening the link on its own. The
- only way to re-open is via the "Open" button after a "Hard Close".
-
- Features:
- -Added a "quiet mode" button to disable notification of PAP
- messages (if successful) and "Idle Timeout" conditions.
-
- 6/28/93
- 1.1.1 Release
- This release has up-to-date documentation and a few
- bugfixes (see below).
-
- Fixes:
- -PPP Server names were not being properly added to the Menu causing
- problems when they contained the Menu Manager's special chars.
- -Added a hack so that IPRemoteAT could work when using the
- Printer Port for PPP.
- -The control panel was not updating the user items in certain
- cases.
- -The control panel edittext fields did not allow chars > 127.
-
- 6/15/93
- 1.1 Release
- MacPPP 1.1 is being released without new documentation as I
- did not want to delay it any longer. Updated documentation will
- be released when ready. In the interim, see below for fixes and
- new features. The Copyright notice disclaimer in the docs needs
- to be ammended to read:
- "... an unlimited license for use and redistribution of the
- executable program provided that it is not sold, either as-is
- or as part of another product, for profit. Charges to recover
- the cost of duplication and distribution are permitted."
-
- Fixes:
- -The Open/Close logic in the Control Panel was too confusing.
- You may now open/close PPP independently of an application.
- -PPP was not properly NAKing the Authentication option (when
- CHAP was requested). Now correctly NAK's with PAP.
- -Calling CloseDriver during interrupt time was causing problems.
- The Close routine now closes immediately (rather than sending
- a Terminate Request) during system time.
- -Requiring users to not use AT in Modem Init was too confusing.
- The code now checks if the AT is already there.
- -Much of the text was stored as literals in the source. These
- have now been moved to resources.
- -Increased the serial driver receive buffer to 1536 bytes to
- reduce software overruns on slow machines.
- -Added a delay before attempting to redial when busy.
- -Bug in state machine caused interoperability problems with
- PPP implentations using the old state machine. (i.e. KA9Q)
-
- New Features:
- -A number of routines have been re-written to improve their
- speed and reduce the code.
- -A Hangup (+++ ATH) can now be initiated on Close by selecting
- the "Hangup on Close" checkbox in the Control Panel.
- -The CommToolBox is now used to get the names of serial ports
- and their associated drivers. The code will work without the
- CommToolBox, but only refers to the Modem and Printer ports
- by default.
- -An idle timer is now provided in the Control Panel.
- -An LCP echo request mechanism is provided to detect dead
- sessions. This is also configurable via the Control Panel.
- -timeout and number of retries may be configured for LCP, IPCP,
- and PAP.
- -Both PAP id and password may now be configured. Password is
- blanked, but stored as cleared text. If password is left
- empty, it will be prompted for at connect time.
- -Multiple PPP server definitions are supported.
- -modem connect and string wait timeouts are configurable.
- -The code does TCP window size limiting to improve TCP
- performance and get around MacTCP's re-transmit timer.
- -The connect script now treats the `\` character as special.
- These are somewhat C-like in convention, but note that it is
- a subset and that some characters have been redefined for other
- functions.
-
- \r - carriage return (13)
- \^ - the literal '^' character
- \\ - the literal '\' character
- \nnn - an 8-bit octal value
- Additionally, for "out" strings the following have significance:
- \b - send a break ( 100 milliseconds)
- \d - delay for 1 second
- \t - invoke the terminal emulator
-
-
- 4/14/93
- This is still MacPPP 1.0 (same code) but now with
- new-and-improved documentation from Susan R. Harris.
- The documentation and get info fields now have the officially
- sanctioned copyrights. I also got rid of the scammed icon
- and changed it to be an original design. Its supposed to be two
- phones if you can't tell (so much for my artistic talents).
-
- I'm still working on the code when I have time, but I'm not sure
- when I'll be coming out with the next release.
-
- 1/5/93
- 1.0 final release
- Fixes:
- -30 second timeout for modem connect was causing problems.
- -Bumped the timeout up to 90 seconds. Also increased timeout
- on waiting for dialog strings from 20 to 40 seconds.
- -Lower case AT commands causes problems on certain brain-dead
- modems. Switched to upper case commands.
- -File locking on System 6 machines caused problems when
- trying to start PPP while the control panel was open.
- -Insufficient input buffer for serial driver caused rx overruns
- when running above 19200 on slow Macs (SE's, Plus's, etc.).
- Increasing buffer size from 384 to 1024 solved problem.
- -Netmask was always set to 255.255.255.0. This caused
- problems when assigned a Class A or Class B address with a last
- octet of 0. (MacTCP assumed it was a broadcast address
- and thus invalid).
- -IPCP Config Requests with the old style VJ option were
- dropped rather than rejected. May add support in next release
- for the old style option.
-
- New Features:
- -Added the current states of PPP options to the Statistics
- window in the control panel.
- -Changed buffering scheme to reduce system heap space
- required by about 5K ( now allocates ~16K at startup).
-
- 12/2/92
- 1.0beta Release 1
- Fixes:
- -Problem in LCP which caused the data field of all
- options in config requests to be FF's.
- -IPCP did not do option rejects correctly ( did not
- duplicate option contents ).
- -phone num, modem init, and dialog strings could
- overrun stack when parsed.
- -terminal emulation did not handle backspace characters.
- -Control Panel did not save value of "Default id" field
- in LCP options dialog.
- -Open/Close button events could put PPP in unexpected states.
-
- New Features:
-
- -added <CR> check boxes to Connect Config dialog.
