A couple of ways:
1) Yes you can re-build the kernel. You can turn on the auto-irq code or
change the table of com ports vs interupts.
2) (The best way!) Get the setserial program from fine ftp sites
everywhere. This lets you set the ports and irq's from the command
line. I do mine in rc.
My com3 does have an internal modem on intt 5 and com1 is an external modem
, both work fine.
