If I remember
COM1=ttyS0 io 3f8 irq 3
COM2=ttyS1 io 2f8 irq 4

this is the *default* very compatible settings.  As for setserial it has
caused me tons of problems before so I removed it, leave the serial port
configuration to the kernel :)

alex[alex]@digriz:~$ ls /dev/ir* -l

(as you probably have been posted) but what you need to do, for each of them
is

mknod /dev/ir<whatever> c 161 <second>

where <first> would be the second number after the root column, so for
ircomm0 it would be 0.

Once this is done the serial port emulation is done with ircomm0 (after doing
an "irattach /dev/ttyS1") or something.

If you need more details do ask
