Sorry, I meant to put the output of $ dmesg | grep ttyS in my post!

$ dmesg | grep ttyS
ttyS0 at 0x03f8 (irq = 4) is a 16550A

So it picks it up fine, only I beleive it doesn't register the 
device in /proc/interrupts because there was no cable attached
at boot. What I wondered was could I get that entry into
/proc/interrupts so the kernel knows about com1 without
rebooting so I can use to to make a connection over a null
modem.

I'd only start worrying if you know less about serial ports
than me ;)
