Freerunner, Jalimo, rxtx, GPS

[Jim Ancona]

You don't say which distro you are trying this on, but my guess is
that you are fighting with gpsd or frameworkd for access to the GPS
serial port. You probably should be talking to gpsd/ogpsd or via dbus
to the framework, rather than directly to the serial port.
