I/O through the LPT port.

I've bought a K8000 Kit from Velleman. That's an interface specific for domotica. That interface is connected to my computer through my LPT1 port. Is there somenone who knows how to handle parallel communication in Jave ?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Only through a native interface to the host operating system.  Java provides no built-in capabilities to access hardware directly.

You can always do a open file on the LPTx you need, if it's for simple use. Otherwise you need to write C/C++ DLL to the host operating system, and access it with the JNI (java native interface).

Here an example for LPT1 :

public void printLTP1(String OutPrint)
{
  if (OutPrint != "")
  {
     PrintWriter out = null;
     try
     {
        out = new PrintWriter(new BufferedWriter(new FileWriter("lpt1")));
     }
     catch ( IOException e)
     {}
     out.print(OutPrint);
     out.flush();
     out.close();
}
