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 ONLY.....
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.<<<
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.
>> PORTS <<
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. 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. Use SETUP for the FAX, & PORTUTIL for
DATA to change IRQ's.
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. Always try
COM3 and COM4 (and IRQ settings) before deciding the modem is bad.
