Hi all, just a quick question, no it's probably been asked a million times
before.  I have a cash draw that I need to interface with a PC via the
parallel port.  Made a transistor switch to activate the relay but I need to
raise the voltage on one of the pins on the parallel port.  Using C++Builder
6 Enterprise.  Can anyone point me in the right direction with interfacing
to the parallel.  I ssem to remember, years ago, asm but can't quite
remember.  I really would still like to use the port of printing as well.
Is there any pins that aren't used that I can impliment.

Thanks in advance,

Kevin
