    The Bindings provide a low level interface to work with your serialport. It is possible to use them alone but it's usually easier to use them with an interface.


    Developing node serialport projects

    1. Clone this repo git clone
    2. Run npm install to setup local package dependencies (run this any time you depend on a package local to this repo)
    3. Run npm test to ensure everything is working properly
    4. If you have a serial loopback device (TX to RX) you can run run TEST_PORT=/path/to/port npm test for a more comprehensive test suite. (Defaults to 115200 baud customize with the TEST_BAUD env.) You can use an arduino with the test/arduino-echo sketch.
