I am looking for as detailed information as possible concerning programming
the PS/2 (micro-channel machines) parallel ports to operate in an interrupt
driven mode.  I am particularly interested in examples of interrupt service
routines.  It seems that there are different issues which need to be addressed
on micro-channel machines which have level sensitive interrupts vs. edge
triggered interrupts on standard PCs, with respect to handing the end-of-
interrupt, resetting the port, etc.

Any and all information will be appreciated.

Thank you in advance.
