I wonder if anyone know anything about running split-speed on a
PC-XT without having a splitspeed-converter? I only have one RS-232
serial-port and my idea is to have a keyboard interrupt, programming
the 8250 for 75 baud, send the character and then reprogram the 8250
for 1200 baud. Of course, data will be lost if I press a key while
receiving characters, but I don't mind. That problem depends on what
kind of program I'm running.

Please send answers via Email.
