I am sorry I had to post this to the net but I was unable to mail it
to polak@BRL

1.  Yes, I believe there are telephone networks established for the
deaf.  One minor problem is that a different set of tone is used for
deaf communications than the 103 tones.  I believe the tones are
1400 Hz for mark and 1800 Hz for space.
2.  There are Public Domain RTTY programs available which use the serial
port of the IBM-PC.  These programs provide the BAUDOT-ASCII
conversion.  The program is available on a lot of the bulletin
boards around the country.  I believe I have seen it on the HAM
Radio Net bulletin board at 1-203-665-1114.
 
I hope this helps.
