This stuff is in the file /etc/rc.boot/0setserial on Debian systems.
Modify it to suit your system.
Also, you need to make sure you have no IRQ conflicts with other devices.
A few programs may work fine in DOS/Windows with IRQ conflicts, but
probably things will not with Linux. First off, I would try the AUTO_IRQ
option as Susan mentioned. But if you have problems, then I would suggest
investigating whether you have IRQ conflicts.
Typically, IRQ 4 is used for COM1, so it probably should not be used for
COM3. COM2 usually uses IRQ 3. IRQs 5 and 7 are usually safe to use for a
modem on COM3 or COM4. However, if you have a sound card, it probably uses
one of these so you'll need to find out which one it uses then use the
other one for your modem. Generally, IRQs are changed on an internal modem
with jumpers. Look in your modem manual for details (sometimes the cards
are labeled too). Then modify /etc/rc.boot/0setserial appropriately.
