I've had relatively good luck in writing simple terminal routines for PC-compatibles utilizing the BIOS interrupt 14h. But now I have an XT clone with 2 serial ports (COM1 and COM2) and an internal modem attached to COM4. My old routines don't work, even when I specify 3 or 4 in the dx register for the BIOS routines. Can the BIOS routines work for COM3 and COM4? What do I need to do to get to them? Thanks in advance. -- Ted A. Campbell | Duke Divinity School | Durham, NC 27706 | email: tcamp@ecsvax |
