        If you get a CAS SUBMIT FAILED message check the following:
See if you have any periods, commas (etc) in the number you are dialing,
or in prefix in options screen. Remove them and re-try.
     Too many .QUE files may cause this. Use DOS DEL command to remove  the
older QUE files (old faxes).
     Also  check TSRs.      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, as
well as some 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.
