[aprssig] USB interface to d700a

[Walden, Lee]

Both the 276C and the 376C have two NEMA serial ports IN ADDITION to the
USB to PC cable for uploading and downloading data to the unit. In
addition a number of the new Nextel models have GPS built-in and can
output NEMA to external devices for tracking.
