Just how good do you want a dumb terminal emulator to be? I think I've got
something here (I'd hafta dig thru my grab bag) that is a VERY dumb
terminal emulator. About all it does is send and receive characters — no
function keys, macros, or even cursor addressing. But it does use
interrupts for the serial input. I'll dig around. Let me know if you're
interested.
You also might want to look at the TALK program that Ray Duncan presents in
chapter 5 (Page 99) of "Advanced MS-DOS" (that book has a fantastic amount
of information).
