I don't think so.  I've been begging writers of the software to produce
a Baudot output on a wire when receiving, but so far have had no success.

The now-ancient K6STI RITTY sofware did do that (at my request) but is no
longer available, more or less driven out by all the free software and
by the author's disgust at pirated copies.  And it was never updated to
run on anything but DOS and anything but a Soundblaster card.  I have an
old DOS machine that can still run it.
