- 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.
