     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.
     >>>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.

                             MEMORY

     Memory  is  not a straightforward computer  feature.  Normaal  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  HI
(extended/expanded)  memory.  Then  as the program works on  the  data,  it
switches  'pages' of memory (16K blocks) from HI memory  into  conventional
memory  while  it works on that section of data. When  that  section  isn't
needed it swaps that back into HI, 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.
