     In  your  CONFIG.SYS and AUTOEXEC.BAT there are  commands  and  device
drivers  that  load when you boot your computer, If you  get  unpredictable
results,  or  out of memory messages (etc) then you can  re-configure  your
computer.  To test if a device or TSR (resident) program is  causing  this,
you can put REM in front of the line in either of the above files. You  use
an ASCII (plain text) editor or your wordprocessor in plain text mode.

an EXAMPLE......
REM DEVICE=C:\DOS\ANSI.SYS

     This  is  only an EXAMPLE, because ANSI.SYS is always OK  to  have  in
there.   The  most  likely to cause problems are  Windows  (anything),  and
drivers for mice, virus checkers, screen savers, etc.

     >>>Another IMPORTANT thing to check is that BUFFERS= and FILES=  are
35  or  higher.<<<

    **Using  the Dos MODE to direct to COM1 (from say LPT1) ALWAYS  locks
Epressfax.  Also  NAV  (Norton Ani-Virus) must be put at the  END  of  your
Config.sys  file. Some other Anti-virus will always stop an  incoming  fax.
Another problem is screen-savers.

                             MEMORY

     Memory  is  not a straightforward computer  feature.  Normal  memory,
where  computer  programs run, where the OS (operating system)  and  (many)
device drivers reside, is limited to 640K. The extra 2meg or 4 meg is  used
as temporary storage by certain programs, which are running in conventional
(640K)  memory and then swaps blocks in and out. The more programs (&  TSRs
and device drivers) you load, the less room there is in conventional memory
to  operate. Somewhere along the line the system will lock or crash if  you
keep adding programs into 640K.
************************************************************************

     If  you  have an internal modem, it must be set for COM4  90%  of  the
time.  Most  computers  have serial-port 1 and  2  already  built-into  the
computer.  A  serial port is just a built-in comport. So you cannot  set  a
modem to be the same comport (1 or 2). Try com4 then com3, see your  manual
for jumper settings.

     There seem to be some video cards using the COM4 address, which causes
the modem to fail on COM4. In that case try COM3 with IRQ 5 or 2 (see  your
manual).  *>> Don't forget the software must also be told when  you  change
IRQs. <<*

     Sometimes one internal modem/or model of modem will work in spite of a
conflict, when set for COM1 or COM2 when there is a serial port (often this
will  be a 2400 modem). Always try COM3 and COM4 (and IRQ settings)  before
deciding the modem is bad.

     A  slot in your computer is NOT, has NOTHING to do with  the  COMport!
The  COMport is what YOU set ON the modem, via jumpers. Some older XT  type
computers  (and an 'odd' new one) won't allow you to 'skip' a port. ie;  if
you have 1 and 2 the next MUST be com3, not com4. Then you'd use com3/irq5.
