FM> Yeah, it's not hard, you just have to keep flipping the modem

Thats a different problem, support for 1200/75 on the serial port.
Modem modems handle that themselves, talk 1200/1200 over the serial
line, and still support 1200/75 on the phone line. You havent needed
to do that funky stuff since manual modems, all the Hayes command
set supporting modems do it auto.

FM> I even had a couple of programs somewhere which do so.
FM> Very basic. At least one was even written in C, from memory.

The other approach is to just wire up a serial card so you use the
baudrate generator off one port for the Rx clock with the 75 baud.
So you program the speed in each port simultaneously and the uart
you are using just has two separate baud rate clocks instead of
having them tied together.


I've ignored all you pathetic coat trailing, even the pensioner
does it better, and thats not saying much |-)
