Is it possible to communicate over a machine's serial port through JavaScript?

I have to write a short program that sends data to a microcontroller over the serial port that has a GUI and is cross-platform compatible, and I really don't want to use Java's Swing.

JavaScript itself doesn't have any built in functionality to allow you to access the serial port. However, various JavaScript engines (v8, rhino, etc) allow you to write your own custom native objects.

You might want to check out node.js, which is a JavaScript library for v8 that's focused on writing server-side code (rather than web browser client code). It seems that someone's already written a serialport package for that:
