Yes.
I used to run 0.0 with 4 ports. However, I forgot to save my system
configuration for doing that, and I seem to have problems now with IRQ2 vs IRQ9
so it's only three ports for now.
Simply add another line in your system configuration with the appropriate
IRQ and I/O port and mkdev another com in /dev.

Hmmm... coming to think about it, I think there was some other .h file I had
to twiddle a bit to get around the IRQ2/IRQ9 nuisance.

Hope that helps a bit
