An anon source corrected me (i should have experimented), you can
keep COM2 available.
To add a PC compatible serial port (fax/modem board):
You can do this. Just set the modem to an unused irq, and do an
isacfg like:
isacfg -mk -slot 1 -handle COM4 -etyp 1 -enadev 1 -irq0 5 -iobase0 2e8
Then boot genvmunix, and the system will see an 'ace2' device (you can
also configure an 'ace3' device). Build a custom kernel, and make the
new device for ace2:
# cd /dev
# ./MAKEDEV ace2
This will make a tty02 device (tty00 and 01 will still be available
for external devices).
If you have allready done the add_fax command, then at '>>>' you can do
the following to re-enable COM2 and change the irq for COM4.
>>>isacfg -mod -slot 0 -dev 3 -enadev 1
>>>isacfg -mod -slot 4 -irq0 5
