I need to trigger a program to run with a contact closure that will interface through a parallel port. I've never done anything like this before. I've found some C# program stuff, but I've never worked with anything outside of QM. Please help me through this.
Here are some things I've found so far:

http://logix4u.net/Legacy_Ports/Parallel...NT/XP.html
http://www.hytherion.com/beattidp/comput/pport.htm
From what I understand, parallel ports use a high and low voltage (0 and 5V) to send bits of data. So I am pretty sure, but not positive, that the contact closure will just send a high signal on just one of the pins. I'll just need to grab that as a trigger to fire a program that will play audio.
Is there anyway to do this with just QM or do I have to get into other languages.
Thanks for any help,
Jimmy Vig
