Greetings.
I believe the correct word is 'teletype' , Telex a brand...
I never had the opportunity to disembowel nor learn much details of its inner workings. They were not cheap nor found as dumpster candidates. Few business offices had them. Have a faint recall about them.
As transmitting, I suppose it was just as a telephone for dialing; then choose typing or feeding the perforated paper tape, (that by the way I was able to read ! Not fast, but able). I do not know if there was an acknowledgment protocol after dialing.
As receiving; the thing was able to work unattended; when a call was received, -never heard a 'ring'- went 'off-hook' by itself, started typing and went on-hook at the reception of some other ending protocol ?
Had a telephone pair from telco and 120VAC plug. I think.
Suppose there is some operation general description somewhere on the web; but, what do you know about them ? Just nostalgic.
