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.
