LPT ports in C#

Question

I'd like to send some instructions while one of pins of LPT port is on.

I was trying to do something like this:

When LPT port 379 (889 dec) is different from dec 120 then stop doing part of code.

while ((PortAccess.Output(889,120))

I don't know how to do it. I was trying to do something with construction:

while ((PortAccess.Equals())

but you need to compare 2 objects..

I suppose it must be very simple solution for this problem.. :)

I didn´t found PortAccess in my Framework 4: What library are you using? — nabuchodonossor, Jul 18 '11 at 08:32
@nabuchodonossor It's a code snippet wrapping inpout32.dll, found in various places like in http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/56ae3e6d-999d-4260-b19c-934775a9206a/ — CharlesB, Jul 18 '11 at 08:53

I think you will need PortAccess.Input:

while (PortAccess.Input(889) == 120)
{
   // do stuff
}

This assumes that "PortAccess" is a wrapper around the native inpout32.dll such as described in this tutorial.

PortAccess is not a standard library, please provide more info – CharlesB Jul 18 '11 at 08:38
