      I've never done it and am not sure about the parts but there is a
   program that you use to convert the PC's ASCII to Baudot and that uses
   the cassette port.  Ask the SysOp of your board (in the 'msg's to/from
   the SysOp area, not here) if s/he has a program called TDD54.  If not
   s/he can FREQ it from my board as  TDD54.LZH  12K.  I am running a plain
   Opus and a HST modem.  There may also be newer versions of the TDD
   program that I haven't found yet.
      The main reason that very few people use it is because no one has a
   computer with a cassette port anymore.

The latest version of that program is TDD56. It can be downloaded from the
HEX BBS (use 1200 baud on (301) 593-7357) or you can mail me a blank
floppy and I'll be happy to load the software and mail it back.
The file is called TDD56.ZIP and is in file area two. It also includes a
similar program (by the same author, John Spalding) that runs on the Color
Computer using the same telephone line adapter. The plug is compatible with
both computers, as I recall. The CoCo version is called TDD34.

Like the earlier (TDD54) version this file includes complete documentation
for both programs that describes the phone amplifier and what you have to
do in order to make it work.

...

I recommend the 1200 baud line on HEX, if you decide to download, because
my TDD modem got zapped during a recent thunderstorm. That line (593-7033)
is temporarily connected to a Hayes-type almost-compatible which doesn't
handle 300 baud in the Hayesian manner, hence this line is 1200 only and
does not support downloading. I hope to get the CM-4 going shortly.
