Re: Text editting
You missed out 110 and - my favourite - 134.5 baud.
Typically asynch terminals would do either hardware (X-on/X-off) or software (Control-S, Control-Q) flow controls.
Terminals that would only do software (and I recall working with a VT102 "clone") flow control posed problems for software - the emacs editor was a prime example - which used just about every key combination for something. I recall writing an emacs extension for those terminals. Don't, after 30 years, recall any details...
