I can't help with the softwear for the terminal units to display on the 
computer. but if you go here:

Look for a program called MMTTY for just the teletype mode.  Free program 
and very good.

I use a st-6 to feed the model 19 I have and don't put it through the 
computer.  I have played with using a sound card program and feeding the 
audio tones in and out of the st-6 to and from the computer sound card 
program.
