That's an earlier version of the test program, empegTaxi is the one that supports the command system mentioned in the readme... =)
That version requires a click on the to file box, you then cat the file to /dev/usb and when it completes click the checkbox off again...

I'm playing with the serial stuff at the moment, so I'll keep the suggestions in mind... =)
