Error Handling

All functions in Node-Serialport follow two conventions:

  • Argument errors throw a TypeError object. You'll see these when functions are called with invalid arguments.
  • Runtime errors provide Error objects to the function's callback or emit an error event if no callback is provided. You'll see these when a runtime error occurs, like trying to open a bad port or setting an unsupported baud rate.

You should never have to wrap a Node-Serialport object in a try/catch statement if you call the functions with the correct arguments.
