Is there someone who knows how you can easily read data from your parallel
port? I'm stuck. I can find 1000 examples of applications that access the
serial port but none that access the parallel port.

Thx in advance

"JavaTM Communications API

The JavaTM Communications API can be used to write platform-independent
communications applications for technologies such as voice mail,

This version of the Java Communications API contains support for RS232

What more do you want??

Sorry but I use this API allready but it isn't that simple. The parallel
port isn't well enough supported. I can find enough examples of parallel
port programs that use this API that write to the parallel port but no
examples that read from it. I have searched endlessly but didn't find
anything.

Ahh okay, I misunderstod you.
I have used that API a little my self, but only the serial-part.
But as far as I can read in the API, you can replace SerialPort with
ParallelPort in all your examples.
Honestly I can't see what your problem is. As I read the API, it is
straight forward, an the parallelport should work just as the serial
counterpart.
If it's because your are unfamilliar with Java as a hole, then you
probably should start with something simpler.

Thx

I know what my problem is. I used the API perfectly but it seems that my
parallel port doesn't support reading. Strange like hell and very annoying
because I have to write an application that reads from it

Check your BIOS-settings. You need ECP or EPP capability.
Standard/Normal is write-only.

I changed it but it gives me the same results. Something with the parallel
port driver maybe. I heard that many drivers don't support reading. That's
just nice...
