This sounds like an IRQ conflict.
Your serial port (that irtty uses for the SIR interface) is most likely set
to IRQ 3, the default for /dev/ttyS1 and ttyS3.
In my experience it is also quite common for PCMCIA/CardBus-networking cards
to have IRQ 3 assigned to them by Card Services. The simple solution is to
exclude IRQ 3 from the resource pool available to Card Services; in the file
/etc/pcmcia/config.opts, add a line reading:
exclude irq 3
and restart cardmgr, hopefully this solves your problem.
