Serial Chip
Support Routines
The files in this archive are a collection of tools I have used to
muck about with serial i/o on the PC. The code compiles under
TurboC V1.5 (and also 2.0 I think), as well as Microsoft C V5.x,
DataLight C, and Zortech C. The various makefiles are included to
make life easy.
This code is copyrighted by myself and you may use it in any way
you see fit as long as you don't charge money for it and as long
as the copyright notices remain in the sources.
There are several programs which can be made:
1. MDM_INIT - a little program to both tweek the serial port
and initialize a modem. as an example if you had a Hayes
on COM1: and you wanted to set it up at 2400 baud
autoanswer you could enter:
mdm_init -b2400 -pn -d8 "S0=3"
2. MONITOR - looks at the data on a serial line and
displays the data on the screen (or if you redirect
stdout, it will place it in a file). Use the command
monitor ?
to get a succinct description of the command line
arguments.
3. VT100 - a real simple vt100 terminal emulator - all it
does is more or less emulate a vt100 (no alternate
character sets and it's missing some (most?) of the DEC
private stuff). <Alt>F10 exits the program, <Alt>F9 spawns
DOS (use the dos exit command to get back to the program),
and <Alt>F8 sends a break. Use the command
vt100 ?
to get a succinct description of the command line
arguments.
