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. -- Allen R. Shuff -- AI4G -- 919-228-4318 (Cornet 291) ...![ floyd clyde ihnp4 mhuxv ]!burl!ars
