I got this diff closer to "ready for prime time". So now there's a config.ini option here for "coldstart" (defaults to true, setting it to false enables the code to send "don't coldstart" to the gps receiver), and one for "serialport" (which takes a path to an alternate serial port, if you've done something like hook a gps receiver up to the tuner serial port and rename the device)

However before I send it on to Jan I want to do a bit more.
