See the parsers section for more information on parsers and the NodeJS stream documentation for more information on the data event. ... The disconnect event's callback is called with an error object. This will always happen before a close event if a disconnection is detected. ... The close event's callback is called with no arguments when the port is closed. In the event of an error, an error event will be triggered ... The Binding is how node SerialPort talks to the underlying system.
