Thanks for all replies to my question! There is no consensus wether 75/1200baud
on the Amiga is possible, but I will outline the major ideas:

1. NO, it's not possible.

2. Well, no, but if you use the serial port for receiving and hook up
   transmitting to some other port on the Amiga doing the 75-baud part, 
   it should work fine.

3. Use a 75/1200 modem with 1200/1200 buffering. [Ok, so you loose the part
    about it being cheap, but it does work...]

4. Try just what you said: software; when transmitting, send 16 MARK-bits or
   16 SPACE-bits for every real bit you want to send. Stop-bits MIGHT foul
   this up, but there you are...

5. By-pass the serial.device to get rid of start/stop-bits, then as in 4.

6. As in 4, but I know, it will work like a charm!

Well, I will defenitely try the last three. First, though, I must get my hands
on one of these modems, but it shouldn't be too hard, since there are quite
a few of them here in Sweden. Again, thanks!

    I lost a letter from somebody in Canada asking about the mentioned videotex-
    program. If you'll just mail me again, I'll get back to you.
