Example 3.8. Command showing DG-100 download and erase on Linux

`gpsbabel -t -i dg-100,erase -o gpx /dev/ttyUSB0 outputfile.gpx`

The DG-100 provides a physical USB interface to the host computer, but internally it uses a Prolific PL-2303 chip to do this. So you must have drivers installed on your computer to recognize the PL-2303 and provide that data as a serial port to software like GPSBabel. Such software comes with the unit for Windows. Prolific provides software for Mac OS/X, but unfortunately their driver has a defect which makes it unusable with GPSBabel.

### `erase` option

Erase device data after download.

This option erases the track log from the device after download.
