This is typically a problem with a modem ( fax ) that does not negotiate 
properly.  I experienced this problem wayyyy back with Flexfax & a 
Practical Periphals Fax modem.

If the fax appears almost perfect, but "shrunk" to 1/2 the size in the
vertical aspect, then this is the same problem.

If the fax is "scrambled", and un-readable, then it is a flow control 
problem.  

I used the "tiger.ps" file that comes with ghostscript as a test file, 
it really hammers on the fax modem & tests handshaking to it's fullist.

It typically has something to do with resolution ( as you stated below ),
though with a Multitech modem, I am REALLY suprised.  I have a 1432 and
several of the 28.8 ZDX's, and they work flawlessley ( sp? ).

The problem is with a broken FDIS command.  Sam did put in a workaround 
in the code, but I am not sure it is applicable, as your modem sends
properly.

You might want to read up on:

Class2DDISCmd:		AT+FDIS		# enable workaround for broken +FDIS

But I would check you eprom levels first.
