Class1TCFRecvHack is really only for debugging, anyway.  *Some* (few) 
installations may need to use it permanently, but that's just because 
the real fix isn't yet available.  (I'm working on it.)

Yeah, these are traditional USR problems.  The modem firmware "crashed" 
there.  You can see the garbage as it resets itself.

Some people have reported that not using +FTS/+FRS have worked around 
this issue.  Some people have reported that a flash upgrade from USR has 
helped them.

People who are serious about faxing, though, use modems from 
manufacturers who are also serious about faxing.  USR is certainly not 
one of those manufacturers.
