I believe that some high end modems already do that.  From what I understand
the high end Zyzel (?) modem has two cheap DSPs, a 68000 and a ROM.  A modem
upgrade usually consists on buying a new $35 ROM.  Of course the modem is
expensive to begin with....of course it's also really cool..fax modem,
alternate ring detection, caller ID, supposedly can digitize incoming voice 
messages...wish I could afford one.

I have heard that there is doubt that the 56001 could do a 9600 baud modem
and do error correction and detection at the same time.  Anyone know for
sure?  I've heard plenty of people talk about implementing a modem on the
56001 (when NeXT debuted the slabs, when Cork was talking about releasing
an Apple CI clone w/DSP, now,  and at various other times in between....)
but have never heard of someone actually *doing* it.  Does anyone know
(with some degree expertise) just how good a modem the 56001 could make?
If it isn't at least 9600b with V.32,V.42 then by the time you bought the
program and bought the hardware to hook up the phone, you would probably 
be getting into the price range of a real modem.
