Accessing the PC parallel port

Hey Delphis

I'm from Aalborg University in Denmark, and I'm writing a program in Delphi
3.0.
But I can't figure out how to program and access the PC Parallelport (SPP),
is there somebody who can help me?

If You can send me some exampels or links to some sorce codes, it'll be
superb.

Thanks alot
/Daniel

Re:Accessing the PC parallel port

You didn't say which operating system you are working under.....

It it's Windows NT then you have a problem, in Windows NT the user isn't
allowed anywhere near the core of the system, so here you have to write
a hardware driver (very complex) or download an existing driver.
TVicPort is such a driver, it can be found at
http://www.entechatiwan.com/tools.htm and it costs a few dollars, maybe
you can find a free one somewhere...

If you are working under Windows 95/98 you're probably able to access
the port directly. I'm don't know if the "Port"-command is available in
Delphi 3, if not you might be able to solve it with inline assembler or
download a component that will give you a "Port"-command. You need to
know the base address of your parallel port and the offset addresses for
the different pins, this information can most certainly be found on the
internet.

Hope this helps
