access the parallel port

Hi everyone. For a project at college, I need Blitz to be able to access the parallel port for both input and output operations. I know Blitz can't access the port directly but I was wondering if there were any DLL's or something available anywhere that I could call from Blitz which will allow access.

I would be very grateful if anyone can tell me where I could find something along these lines, and how to use it if possible.

Thanks in advance for any help.

Using OpenFile on LPT1: or whatever has been known to work (WriteByte, etc, placing output to a printer). Direct port access is tricky: under Win9x I believe you'll have to look up the port address in the registry, whereas under NT/2000/XP you actually need a device driver to read/write directly to hardware!

There's a slightly illiterate discussion here that seems to cover it...

You'll probably need a C/C++ DLL to be able to write directly to the port too. I recommend trying the LPTx: method first!
