- From highest to lowest priority, the interrupts on an ISA system
- are 0, 1, 8 through 15, and 3 through 7. Several of those are not
- available on the ISA bus, as they're reserved for system use.

- COM1's standard IRQ is 4, while that of COM2 is 3, so yes, COM2
- has a higher interrupt priority than COM1 if both are configured
- to use the usual interrupts.
