Example:
Enter the following command to enable the SBAS messages to port B.
$PASHS,SBA,DAT,B,ON
$PASHQ,SBA,DAT,<c1>
This command queries the SBAS data message, where c1 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.
$PASHR,SBA,DAT
The response is in the format:
$PASHR,SBA,DAT,d1,d2,d3,s4*hh
Table 9.11 outlines the response parameters.

or OFF, and f1 is the optional frequency setting for the output ranging from 0.05 to
999 seconds depending on the measurement update rate option installed. If the
