6.4.1 $JASC
Using this command, you may turn GPS data messages on at a particular update rate or turn it off.
When turning messages on, you have the choice of various update rates available, depending on
what your requirements are.
This command has the following layout.
$JASC,msg,r[,OTHER]<CR><LF>
Where ‘msg’ is the name of the data message and ‘r’ is the message rate, as shown in the table
below. Sending the command without the optional ‘,OTHER’ data field will enact a change on the
current port.
Sending a command with a zero value for the ‘r’ field turns off a message.
