Using the parallel port of a PC, and VB.NET 2003 to write the application, I want to detect a pulse/signal of 5vdc at the port. When the pulse is detected I want to count it, then perform a calculation in a VB.NET 2003 application which yields an integer value. Then whatever the integer is, I want to send that many pulses out the parallel port to a switch.

Example:
pulse 1 detected>calculate> get 5>send 5 pulses out and blind an Led 5 times.
Pulse 2 detected>calculate> get 9> send out 9 pulses.

and so on.
This is for an invention I am building to be controlled fro a PC.
Any help is greatly appreciated!!

Thanks.

Yes, however we used the FALCON (http://www.cmccontrols.com) to do the real-time controls
