Update Reference file - MPModem v1.60 Copyright (C) M. Jose, 1993
New features, changes and bug fixes
-----------------------------------
This is a full update of MpModem which incorporates or changes many
features of the previous versions of MpModem.
Some of the changes are as follows:
- Major re-work of the MpModem screen to give more information to
the user and even more information to the registered user. (See
MpModem.Doc for full details and explanation of these changes).
- Fixed some bugs in the Ymodem driver concerning the finishing
routines. There still may be problems with some Ymodems - let
me know if this is the case.
- Fixed a minor problem with the calculation of blocks to send/
receive under Xmodem and Ymodem.
- Full optimised support for 16550 (and compatible) UART
buffered chips.
- Full checking for parity and framing errors.
- Now allows for communication ports from 1 to 8.
- New compression technique based on Jmodem and adapted for use
under Zmodem.
Note that this is NOT "RLE" as used and copyrighted by Chuck
Forsberg. This version is MUCH faster and what is more, the
source code is available to you free of charge or encumbrance!!
- New fast mode. This is based on PC²'s version which they call
"Turbo". Although this is public domain code, it utilises
Variable length headers which are copyright to Chuck Forsberg.
Consequently, because of this oxymoron, my modified version
DOES NOT use the same approach, but utilitises non-copyrighted
code to achieve the same performance.
Again, the code for this is free of charge and encumbrance.
- New and more user-friendlier configuration program with
on-line help.
- New options in the Configuration program to do the following:
* Set the communications buffer for better response when
multi-tasking.
* Set the FIFO buffer on or off.
* Set the number of bytes in the FIFO buffer (from 1 to 14).
* Change the IRQ and Communication Port Addresses of ports 1 to 8.
- Removed support for RemoteAccess Bulletin Board Systems. This
process added extra program size and a small overhead. It is
better for a Filedoor to be used as the interface between MpModem
and RA. What was previously used was a stop-gap for RA users.
- Removed the added extra of registering the program. This had
served its desired purpose of ascertaining the level of usage
and as such is no longer required. (Should be less of a hassle
for non-Internet users as well.)
