Com1: IRQ 4 0x3F8 - /dev/ttyS0 (/dev/cua0)
Com2: IRQ 3 0x2F8 - /dev/ttyS1 (/dev/cua1)
Com3: IRQ 4 0x3E8 - /dev/ttyS2 (/dev/cua2)
Com4: IRQ 3 0x2E8 - /dev/ttyS3 (/dev/cua3)
The kernel 2.0+ comm port drivers can share interrupts. AFAIK, there is
no longer a reason to assign a separate IRQ to each serial port.
The tool you would use at a command line is setserial. You may override
the kernel's autoprobe with a command line option as well, for example:
append="serial=0x3f8,4 serial=0x2f8,3"
There is far more information in the Serial HOWTO on the Linux
