About the GPS module on TransPort routers

One of the options available on some models is the ability to connect a GPS receiver which enables
the router access to geographical position information. The GPS module may be internal or
external. In either situation, the router uses an internal asynchronous serial (ASY) port for the
connection. The standard way that GPS modules send the data is using National Marine Electronics
Association (NMEA) standard 0183 messages. This protocol is usually simply referred to as NMEA.
Routers offering this functionality support the most common NMEA data messages. These
messages are described below. GPS receiver modules normally accept configuration commands
which specify which of the NMEA messages should be sent to the requesting host.
