[Xastir] GPS Data with an IC-2820H

Well, finally figured it out myself.  The Keyspan software comes with a 
little debugging tool.  Ran it and came up with a device name of 
/dev/cu.USA19H1d1P1.1

I changed the name in the config file and now I am getting the GPS data 
from the radio.

Cheers and 73
