FreeBSD and TTY

[un_x at Safe-mail.net]

I suffered a stroke a while back, and one of the
effects was that it impaired my speech to the point
where all of these automated answering services
cannot understand my answers to their questions.
Even simple yes/no or numbers or whatever they ask.
And I see that many have TTY numbers for deaf people,
and I'm not deaf, but I was thinking maybe I could
make use of them.

Does anyone know if 'cu(1)' can be used?  I do have
a normal 33.6 modem connected to a phone line, and
I tried to research and study to find out how this
may be possible, but I couldn't find clear and
definitive information, but it did seem like TTY
is just a normal dialup connection with a very
slow baud rate.  I guess they also have special
TTY machines, but that is beyond my immediate
ability; without getting into too many details.

If anyone can help, thanks!
