[ale] modem set-up

[Timothy Clark Jr.]

Here are my thoughts... hope they help.....someone correct me if i'm wrong

In later bios revs there is a setting for choosing a PNP OS - Switch it to
off or NON.
Also switch the COM2 port in bios to off or disabled ---- I think you're
modem is trying to use it and its resources.

Standard PC Com ports are as follows:

COM1 uses IRQ4 - IO 3F8 this should be your mouse or ttyS00

COM2 uses IRQ3 - IO 2F8 this should be your modem or ttyS01 this is probably
set on the modem already from the sounds of it.

Try setting it like this and then use setserial.

Again, hope this helps.

> When I did setserial on tty01 (which is set for IRQ 3), I got back
parameters for my modem. This is driving me crazy. How can the system
recognize a modem on ttyS01, IRQ 3, yet the BIOS is telling me I have a
conflict with that IRQ, and as a result, keeps saying that the modem is
busy? Ack.

to class til 7:30. I'll be back to try it then.
