This is the source code for a program which read from OR
writes to the parallel port. The header file PRINTER.H
contains the base address for the parallel port and may
need to be changed depending on your system. Also, note
that this code will assemble as either the "read to"
program or the "write from" program depending on
which is "defined" in the code.

This code was taken from an old magazine a few years ago,
and unfortunetly I don't remember the author, so my
apologies to him/her.

Instructions: The "read from" program scans the parallel
port and updates the screen constantly. To quit the program,
simply hit any key.
The "write to" program initially puts all pins high that can be
put high. Hit the spacebar, and all pins that can be put low will
be put low. Hit enter to exit.
