from alarmdecoder.devices import SerialDevice

def main():
    """
    Example application that prints messages from the panel to the terminal.
    """
    try:
        # Retrieve the first USB device
        device = AlarmDecoder(SerialDevice(interface='/dev/ttyUSB0'))

        # Set up an event handler and open the device
        device.on_message += handle_message
        with device.open(baudrate=115200):
            while True:
                time.sleep(1)

    except Exception as ex:
        print ('Exception:', ex)

def handle_message(sender, message):
    """
