Teletypes use 20mA current loop circuitry, a simple 20mA/RS232 converter
is all you need ($10 - $20). Data is 7 bit ASCII, upper case only.
I have my ASR33 hooked up to my workstation using an adapter and it works
well.

Our sawmill uses an HP-1000 for process control; it
has an infrared
paper tape reader and an ASR 33 Teletype. And they all work. But I'd
like to replace the teletype with a PC. Does anyone know how to make
a PC emulate an ASR 33??
Thanks
