I am interested in setting up a teletype that would print a message straight from the digital signal. Is there software that would decode and send to printer unattended? I thinking of using an old dot matrix printer. Thx for any info. Email to devernham@comcast.net

Too vague. Digital signal. What digital system..
Teletype is either 5 level or 8 level baudeau..

Some older matrix printers were EBCDIC coding.. (IBM)
or later on ASCII..

you have to match the coding to the printer..
Real teletypes can print TTY signals almost directly off the air. You just need the TTY converter. audio to current.

ASCII you would need buffering I would suppose, to collect a stream of data and then print.
data coding ,,to the printer is what you really need to understand to do this.
