Re: Text editting
You missed out 110 and - my favourite - 134.5 baud.
We've got a PDP8/f that's got its serial interface modified for 110 baud, by having a different crystal fitted, for use with an ASR33.
And if you have ever looked under the hood of an ASR33, you'll know why it can't do any speed but 110: its serialiser/deserialiser is a contactor disc driven by a synchronous motor.
Typically asynch terminals would do either hardware (X-on/X-off) or software (Control-S, Control-Q) flow controls.
Err, Xon/Xoff (Ctrl-S/Ctrl-Q) is software flow control. Hardware flow control requires at least RTS/CTS or DSR/DTR to be wired as well as Tx/Rx and Gnd,
