Did you see my teletype page? It has movies of an operating teletype Not too different than operation
in local mode.

It looks pretty marginal, a lot of serial ports aren't going to have the
drive. I made a converter with optoisolators & rs-232 chips etc
which is a lot more complex than needed and also was a little strange since I
made it before I got that degree. If nobody has pointed you to a better one
I can scan my schematic, >15 years ago radio shack had the parts.
