     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 etc. But I'd REM everything not absolutely NEEDED  to  do
your test!

     >>>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
Expressfax.  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 many screen-savers.

                             MEMORY

    If  you have Dos-6.x, I suggest running Memmaker before and  after  you
install  the modem/fax software. Memmaker sets up TSRs and drivers  to  use
EMS  so  they  won't conflict. 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 BY certain programs, which are running  in
conventional (640K) memory. They have special features which can load large
blocks  of data into that  (extended/expanded) memory. Then as the  program
works  on  the data, it switches 'pages' of memory (16K blocks)  from  that
memory  into  conventional memory while it works on that section  of  data.
When  that section isn't needed it swaps that back, and gets another  peice
to  work on. This lets you have HUGE spreadsheets or databases running  yet
only have 640K to run the program(s).
     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. A  loaded
program even not running takes memory. So close each (Windows) program when
you are done using it.
