                   Using an XT with FAX & High Speed Modems

     While it can't hurt to try, you may be disappointed running FAX and/or
Voice software in an XT or 286 machine. Not only the processor is SLOW, the
hard  drive  is not usually fast enough to access the files as  quickly  as
needed. Many XT/286 will have trouble, and the ones that do work are  quite
slow (my 2nd 'fax sending machine' is a 286, so I know). Older machines are
also more likely to have a BIOS with some problems with serial/comports, or
other  things.  Also, Dos 3.3 may work better than a later dos  which  uses
more  memory,  as memory is often a problem. I wouldn't try  any  'serious'
faxing  in  anything less than a 'real' (not an upgrade of XT or  286)  386
computer.  The newer the software, the more likely you will have  problems.
They don't do much (if any) testing on old slow machines.

     High speed modems may also be a problem. I would assume that a 9600 or
14.4  will  be OK. However 19.2 to 28K modems may have  problems.  I'd  try
setting  19.2 and &Q6 (buffering but no protocol), or 9600 and &Q0  (direct
connect).

          Another  problem with older machines is comports. Some refuse  to
allow  you  to 'skip' a port. If the highest is com1 (serial-1),  the  next
MUST be com2, you can't use com3 or com4.

NOTE:>>>  The  Zoom box may say that it will work with an XT or  286.  This
refers to the Modem ONLY. We cannot promise software will work on any given
machine, even a new 386/486 etc.  Software is provided (it is not a part of
the  purchase  price) as is, though we will attempt to  help  you  get  it
working.
