- Hi. I've never posted to News Groups before, so please excuse me if
- I break any rules of netiquette.
-
- I am looking for some free Borland C/C++ or Turbo Pascal routines
- to program the 8250/8251/16550 UART registers and to read and write
- characters to comm ports on 80x86's. Any help would be appreciated.
-
- Basically, it would be great if I had self-contained modules that I
- can call from a Pascal progam to initialize the UART, set the
- data/parity/stop bits/speed/etc, and, of course, to read
- and write a character, and to set and check the handshake signals (DTR,
- RTS,etc.). Hopefully that's not too much to ask.
-
- I've programmed in several languages, including C and Pascal. I've
- also written Motorola 68000 CPU assembly code to communicate with a
- Motorola MC68681 DUART circuit I built. However, I have never written
- C or Pascal to talk to the 80x86-type UART and PC comm ports, which is
- what I now must do (and I must do it soon!).
-
- Thank you,
-
