Ask the Java Communications API * what ports it thinks it has.
// get list of ports available on this particular computer,

Enumeration pList = CommPortIdentifier.getPortIdentifiers();
// Process the list.
while (pList.hasMoreElements()) {
CommPortIdentifier cpi = (CommPortIdentifier)pList.nextElement();
System.out.print("Port " + cpi.getName() + " ");
if (cpi.getPortType() == CommPortIdentifier.PORT_SERIAL) {
System.out.println("is a Serial Port: " + cpi);
} else if (cpi.getPortType() == CommPortIdentifier.PORT_PARALLEL) {

} else {
System.out.println("is an Unknown Port: " + cpi);
}
