Example
Enter the following command to enable the RMC message on port C.
$PASHS,NME,RMC,C,ON
$PASHQ,RMC,[c],
This command allows you to query the RMC message, where c is the optional port
designator for the output of the response. If a port is not specified, the receiver
sends the response to the current port.
$GPRMC
This message contains UTC time, date, position status, latitude, longitude, course
and speed over the ground, and magnetic variation. The RMC message is not output
unless positions are being computed. The message is output in the format:
$GPRMC,m1,c2,m3,c4,m5,c6,f7,f8,d9,f10,c11*hh
Table 4.101 defines the message format.
