hi i am trying to receive some data from a rs232 serial port on a xp machine
i tried the javax.comm but on further reading my understanding is that this is no longer supported/working

so i got the rxtx jar, added it to the buildpath of the project and removed the references to the java.comm stuff....

now when i go to use it i can call

Java Code:
import java.gnu.io;

but i can't import the specific stuff that i need ie

Java Code:
import gnu.io.CommPortIdentifier;
import gnu.io.NoSuchPortException;
import gnu.io.ParallelPort;
from which id like to do stuff like

Java Code:
          //get the parallel port connected to the printer
          port = CommPortIdentifier.getPortIdentifier("COM1");

would appreciate any help
