Is it possible to use poll or select to detect a change in the status
bits of the parallel port? I tried something like this, and took bits
5 and 6 of the status register low and nothing seemed to happen. Is

, or I am supposed to take a
certain bit low to cause a read event? Any help is appreciated.
PPI doesn't support select/poll.
I don't think ere is any support for interrupt based notifications.. The only
