 The interface of GPS.js is as simple as the following few lines. You need to add an event-listener for the completion of the task and invoke the update method with a sentence you want to process. There are much more examples in the examples folder.

+## Find the serial device

 On Linux serial devices typically have names like `/dev/ttyS1`, on OSX `/dev/tty.usbmodem1411` after installing a USB to serial driver and on Windows, you're probably fine by using the highest COM device you can find in the device manager. Please note that if you have multiple USB ports on your computer and use them randomly, you have to lookup the path/device again.

 GPS.js comes with some examples, like drawing the current latitude and longitude to Google Maps, displaying a persistent state and displaying the parsed raw data. In some cases you have to adjust the serial path to your own GPS receiver to make it work.
