My PMMI MM-103 modem supports anything from 61 up to 600 baud, though
anything within this range but considered nonstandard is only
supported between two MM-103's. It uses FSK modulation and the
manual is copyright 1980, though some of the circuit diagrams I have
for it are dated 1978.

My CDC Plato terminal supports these rates:
If receiving at 1200: 75, 120, 150, 600, 1200
If receiving at 1260: 78.2, 126, 157.5, 630, 1260
Also, my International Data Sciences, Modem Test Set supports the
following data rates: 75, 110, 134.5, 150, 300, 600, 1200, 1800, 2400,
4800, 9600. ALso, stop bits can be either 1, 1.4, or 2. This is a
1980's device, with Nixie tube display.
