Hi,
   I'm very new to java and i'm trying to open serial comm ports using the
javax.comm api, when I run the sample programs to print out which com ports
I have, I get nothing. its not getting past the e.hasMoreElements statement.

I can see the "inside port listener" statement print out, then nothing....
any ideas on what i've done wrong.?

ANY help, would be much appreciated.

import javax.comm.*;
import java.util.*;
public class PortLister {
public PortLister() {
Enumeration e = CommPortIdentifier.getPortIdentifiers();
System.out.println("Inside port lister");
while (e.hasMoreElements()) {
CommPortIdentifier com = (CommPortIdentifier) e.nextElement();
System.out.print(com.getName());
switch(com.getPortType()) {
case CommPortIdentifier.PORT_SERIAL:
System.out.print(", a serial port, ");
break;
case CommPortIdentifier.PORT_PARALLEL:
System.out.print(", a parallel port, ");
break;
default:
// Important since other types of ports like USB
// and firewire are expected to be added in the future.
System.out.print(" , a port of unknown type, ");
break;
}
if (com.isCurrentlyOwned()) {
System.out.println("is currently owned by "
+ com.getCurrentOwner() + ".");
}
else {
System.out.println("is not currently owned.");
}
}
}
}
