Hi Michael,
In my modem manual COM ports are defined as:
COM1 Irq 4
COM2 Irq 3
COM3 Irq 5
COM4 Irq 2
as suggested default settings.
Alternate settings suggested as:
COM3 Irq 4
COM4 Irq 3
obviously alternate settings will cause Irq conflicts
if other port with same Irq is being used at the same
time by another device.
Michael, the important thing is that your documentation
explains what the default settings are and what the
alternative options are. It would appear that Irq's
2, 3, 4, 5, and 10 should be available as options
to be assigned to whatever COM port as needed.
Eric
P.S. I appears to me that COM ports 3 & 4 tend to be
non-standard parameters since they are usually
implemented by adding additional cards to the
motherboard bus. I have never seen a computer
originally sold with more than 2 serial/com
ports. I have a computer set up with 2 modems
which use the same Irq but I never use both
modems at the same time so there is no problem
with Irq conflict.
