Hi,
I have this problem. I need to retrieve or send data to/fro the I/O port (parallel port). Most books refer to using the I/O package. However, i have difficulty implementing it to solve my problem. How actually do i specify my data source and destination which is the port itself?
Can anyone provide me with the statements to perform that?

Many Thanks!

You have to attach an input stream to the port.

      String strPort;
      .
      .
      .
      if ( ... )
      {
      strPort = "LPT1";
      }
      else
      {
      strPort = "COM1";
      }
      .
      .
      .
      java.io.BufferedInputStream = new BufferedInputStream(strPort);

      Hope that helps.
