Was it 110, 135, then 300?

It was 45.5, 50, 56.875, 75, 110, 134.5, 150, 300, 600, 1200, 1800, 2400, 4800, 9600 etc etc etc Most of the lower ones were used for Baudot 5bit teletype comms and were commonly referred to as 60, 67, 75, and 100 words per minute. 134.5 is used by some IBM systems (older). Any I missed? Source: Atari 850 interface module operators manual. The 850 can handle the current-loop which teletype use but only on two of the four ports. An interesting note is that the Microbits Peripheral Products MPP1000 series "300" baud modem is adjustable in increments of 1baud making all combinations possible reliably up to about 450baud on a clean line. This was an obviously useful feature if the BBS you were calling also had an MPP1000 modem..... Another use was when the other-end used a modem that wasnt running at quite the correct rate. The Atari 1030 modem runs at 297 and is not adjustable. I'd just set my MPP to 297 and things would go smoothly. More trivia that you probably allready know is that the term 'Baud' does not apply to the newer (2400 and up) modems because these don't use FSCK to move data. They send multifrequency 'symbols' taking better advantage of the audio bandwith of the phone line. Does anyone recall the origin of the term "Baud". I used to know but that was a long time ago. I think it was someone named Baudot? regards, Jeff P.S. I reserve the right to be wrong.
