There are some commands that only operate in the proprietary binary
format... the main NMEA sentences though contain everything you would
normally expect from GPS and spew once per second automatically.  The
binary and NMEA stuff coexists on the same UART.

Some stuff like stashing and restoring the data it took time to get from
the satellites is done in the proprietary binary mode, handy to recover
GPS quickly from suspend for example.
