Subject: Re: Teleprint 390
My 11/45 has a seperate "Paper Tape Advance" output on the console serial
interface, whic is set by writing to a register - I assume that the
Teleprint 390 / ASR33 has either a solenoid drive or a clutch that allows
the tape to advance one character at a time, under processor control.

I just hooked up my Teleprint 390 to my laptop and it works like a
charm, almost 100%. I can type on my laptop and the output appears on
both the papertape as typed. And what I type on the Teleprint appears
on my laptop but what it doesn't do is when I feed it a papertape
output it on the laptop (only parts). It does output it correctly on
the Teleprint itself. Any idea's what might be wrong here ?
I am not a real technical person but willing to give anything a try :-)

Hi
Some computers are especially slow at doing a linefeed to
the screen. I'd think it could keep up with 110 Baud though.
Most teletypes have some way for a signal from the computer
to throttle the paper tape read ( as I recall ). You might
look at connecting some handshake.
You didn't state if it was making mistakes from the first
character or if it read several right and then lost it.
If it read some right, how long does it go before it
makes mistakes? Any line feeds involved?
