Parallel Port Utility

[smil3y]

I have a couple of input/output expansion cards connected to my parallel port (LPT1). I am having troubles with communications between the port and cards and require a utility of VB code that allows me to see what is being passed between the port and cards.

Is anyone able to provide me with code examples or a utility to trap/view this data.

There have been a number of discussions on this subject. Do a quick search on 'parallel' from the keyword search tab at the top of the page, selecting 'this forum only'

There is also a web resource on the parallel port, including a freeware port driver DLL at :
