Parallel Port Trigger

[TheVig]

Thanks a bunch for your help.

I am just trying to figure this out in advance, I don't have access to the Parallel port device I am going to be using, but when I load this up on my computer with nothing in the parallel port I get "Input is: 255" This 255, that's the what I should get in this instance? Then I should see that number change when a signal is received?

Also what are the four values received by SetTimer function.

Thanks again,
Jimmy Vig
