- As far as I know, IRQ2 is used for chaining the interrupt
- controllers in the ISA-PC architecture. So really free interrupts
- are very rare. I think 10 and 11 are "free" on some machines
- (I hope your serial port extension is a 16 Bit card),
- or the interrupt of LPT2, if it is not installed.

- So long
