Help.

I have an application that runs in a tight loop with interrupts disabled.
My problem is:  ending this loop when the user hits a key.

Since the interrupts are disabled, the keyboard interrupt handler is never
invoked, thus the BIOS keyboard routines don't work.

What I need is a way to check for a keyboard interrupt pending:  any easy
way to do this (e.g. what port and bit)?

Any info appreciated.
