If you want to read and write individual lines of the parallel port,
look at the TVicLPT component

http://www.entechtaiwan.com/tviclpt.htm

It gives you complete control (including an LPT interrupt event) over
the parallel port. You can treat the port as a parallel port or a
printer port (reading and writing a byte at a time with control lines)
or as individual pins to set high or low or read their
input state. There is a free version to try out and it's inexpensive
to buy. It will even find parallel ports installed at the high
addresses that the PCI bus and later versions ofWindows insist on (in
addition to parallel ports installed in the old DOS locations of 278,
378 and 3BC hex).
