        return number
    def read_data(self):
        while True:
            data=self.port.readline()
            self.message+=data
if __name__=='__main__':
    mSerial=MSerialPort('/dev/ttyACM0',9600)
    thread.start_new_thread(mSerial.read_data,())
    while True:
        time.sleep(1)
        print mSerial.message
        print 'next line'
