  • switch connect to parallel port

    I need to monitor a switch connected to a parallel port

    Is there any examples showing how to do this

    I think I will need to use the IO.dll

    thanks

    Ralph,
    Yep you are right, you will need IO.dll (or some other low-level dll) to control/watch a parallel port on a Windows NT system (NT4/2K/XP....Not sure if Vista even knows what a parallel port is ) But a Windows 98 System (95/98...I assume ME) you can access the port directly.

    A good starting point would be Lakeview Research - Jan Axelson - Parallel Ports Complete
