Greetings from the void!

Someone called me and asked if there was a way to turn her IBM PC (I think it's 
an XT) into a TDD (Telecommunications Device for the Deaf).  

I explained the problem to her:  PC's use an 8-bit ASCII code, TDD's use a 5-
bit BAUDOT code.  And TDD's also are limited to a single, obscure baud rate of 
45.5 bps.  

I told her that I vaguely remembered that there was a special-purpose modem 
(or perhaps a programmable UART) that did the bi-directional ASCII <---> BAUDOT 
translation, but I couldn't remember the details.

So, anyone out there know the who, where, how, and how much?

Thanx for any info.
