It's true.  The remote really only does support 4800 baud.

Here's the problem.  Notice that the modem responds with garbage at the 
end of the TCF signal.  (The [2:xx] just before the "Problem sending 
TCF data".)

HylaFAX CVS-HEAD now ignores garbage from the modem at the end of the 
TCF signal.  So, you can wait until 4.2.1, you can get CVS-HEAD, or you 
can apply the patch.
