Enumerating serial port (using RxTX)

This is simple code to enumerate your serial port names.

public static String[] listSerialPorts() {

    Enumeration ports = CommPortIdentifier.getPortIdentifiers();
    ArrayList portList = new ArrayList();
    String portArray[] = null;
    while (ports.hasMoreElements()) {
        CommPortIdentifier port = (CommPortIdentifier) ports.nextElement();
        if (port.getPortType() == CommPortIdentifier.PORT_SERIAL) {
            portList.add(port.getName());
        }
    }
    portArray = (String[]) portList.toArray(new String[0]);
    return portArray;
}

If the serial ports are not detected, use this option as execution parameter: -Dgnu.io.rxtx.SerialPorts=/dev/ttyACM0:/dev/ttyUSB0:/dev/<your port name>
