I have done most of the work on the DECmate MODEM overlay, so perhaps I can
help.  You should first check the overlay file to see if it really is
a version that has the most recent DECmate code in it.  The problem is that
the 6120 (PDP-8) processor in the DECmate II handles all the I/O, and in
particular it grabs any XON/XOFF's (^S/^Q) and does its own flow control
without passing them on to the Z80.  It is possible, however, to command
the 6120 to not do this and pass thru everything.  This is what the overlay
does, in the initialization subroutine.  You should look at the source
code in the overlay that you have to see if that feature exists and is
enabled.  If you do not have the most recent overlay, which is called
something like M7VT-4 (or higher), you can get it from SIMTEL20 or 
DEC-MARLBORO.

Incidentally, I have noticed that MDM730 and higher running on 
DECmate's seem to have a problem with passing thru function key escape 
sequences, in particular the direction arrows.  I think it's some kind 
of timing problem, but I haven't pursued it.  I don't *think* it 
affects file transfer.  Personally, I always use Kermit.
