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 to set the jumpers on the Modem). *>> 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. Always try
COM3 and COM4 (and IRQ settings) before deciding the modem is bad. If you
had an internal and took it out, and a new external does not work, you may
need to Re-enable the serial port the modem is plugged into. (see the
serial port manual).
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.
An external modem cannot be set! It uses the address of the comport
into which it is plugged via the modem cable.
