Answer 2

Looks like to need a SerialPortReader which needs to implement a SerialPortEventListener

     public void serialEvent(SerialPortEvent event)
     {
            case SerialPortEvent.DATA_AVAILABLE:
            byte[] readBuffer = new byte[40];

            try
            {
                while (inputStream.available() > 0)
                {
                    int numBytes = inputStream.read(readBuffer);
                }
                System.out.print(new String(readBuffer));

                System.out.println();
                System.out.println("DTR: " + serialPort.isDTR());
                System.out.println("DSR: " + serialPort.isDSR());
                System.out.println("CTS: " + serialPort.isCTS());
                System.out.println("RTS: " + serialPort.isRTS());
                System.out.println();
                outputStream.write("ACTIVESYNC".getBytes());
            }
            catch (IOException e)
            {
                e.printStackTrace();
            }
