WXMODEM 1.08 Nov 1992
---------------------
This driver is intended to replace the WXModem.COM version 0.9
which is the only driver I have ever been able to find!
This version has only two parameters:
1. Way+Port Number.
2. [drv][path]<filename.ext>.
Calling WXMODEM without parameters will display a help screen.
It will attempt WxModem transfer and that failing try to go with
XMODEM-CRC and then fall back to try XMODEM-CSUM.
This version has been optimized and compiled with Turbo Pascal 6.0!
A version compiled with StonyBrook PASCAL+ 6.0i is included and
named swxmodem.exe.
I hereby claim Copyright (c)1991,1992 by L.B. Neal on substantive
improvements over the original code as written by Scott Murphy and
Peter Boswell.
This program is NOT public domain, however permission is granted
for personal use without registration. Use in a commercial, for-profit
or government situation requires a negotiated nominal license fee.
Donations to encourge me to continue improving this program will be
gladly accepted.
I welcome comments, suggestions and application reports.
WXMODEM.EXE requires about 64k available to run in. Error information
will be written to the file WXMODEM.ERR.
The driver supports COM1 thru COM4 on PC/XT/AT type machines. Direct
screenwrites are used for maximum speed. Baud rates thru 9600 work great.
The port is assumed to be initialized and as such the driver probably
will not work stand alone from DOS.
An interrupt driven receive buffer is utilized for fast transfers
without losing characters. It is set at 4096 bytes as provided.
I have included WXR.BAT and WXS.BAT which are examples of how to
call WXMODEM 1.00+ via a batch file. The provided files are setup
for Telix 3.15+ and QMODEM standards and thus probably will need some
modification to use with other comm programs.
NOTICE
------
The CRC calculation procedure in this program is based on the
work of Check Forsberg(DSZ), Stephen Satchell and Satchell Evaluations.
This program is provided "AS-IS" without any form of warranty that it
will do anything at all. The program seems to work as described in this
document, but has NOT been subjected to extensive testing.
