 Instructions for Configuring External Tools for a Model
 
 1. Ensure the model is not open in QM.
 
-2. Copy the Blinky model's settings (libraries/qpn_avr/examples/blinky/.blinky.macos) from your Arduino Sketchbook folder to the model's folder.

 3. Rename the settings file to your model's name (i.e., .mymodel).
 
 4. Open QM and edit the settings from External Tools.
 
-Once you have a working .model file, copy it to other models and use it as a starting point.

 Known Issues
 
-1.  The serialterm External Tool is working by opening a Terminal window. An additional Terminal window also appears and can be safely closed. When the Terminal window displaying the Arduino's output is closed, the port is busy and can no longer be accessed. Work-around is to unplug and re-connect the Arduino from the Mac's USB port.
