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 anerror 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.
