0x2020 is your IO address.

This is in /proc/pci above.

Your IO and IRQ aren't that important as they only set up the kernel serial
driver. with PCI this is done automatically.

These serial ports sould refer to the two serial ports. Are there two on the
mother board and the PCI card is the third.
If your using devfs - /dev/tts/[0-1] are also your serial ports. Look at the
major and minor numbers when you do:
ls -la /dev/ttyS? /dev/tts/*
If you want to check the modem
minicom /dev/tts/0 and try some AT commands (Hayes command set) - ATDT
(number) dials a phone number, ATA answers, google search will give you a
full list.

mknod - shouldn't need to though - they should already exist. Especialy if
devfs is manageing /dev. Look at /dev/tts/*
If you do NEED a third:
mknod /dev/ttyS3 c 4 66

I think from memory there is an edit on the /etc/inittab for a S0 entry with
vgetty on it and the rest is [mv]getty config based.
The documantion with mgetty is useful last I saw - you have emerged mgetty and
looked at /usr/share/doc/mgetty-{version}?
