  + Opening the serial connection from a linux machine will cause the arduino to reset.  This is a [known issue](https://github.com/pyserial/pyserial/issues/124) with pyserial and the arudino architecture.  This behavior can be prevented on a windows host using by setting `arduino.ArduinoBoard(enable_dtr=False)` (the default). See [issue #9](https://github.com/harmsm/PyCmdMessenger/issues/9) for discussion.
