$PASHQ,TCM,[c1]
This command queries the TCM 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,TCM
The TCM message contains status information for the remote differential station
as well as information on the transmitting base station, such as the base station ID
number, base station health, remote station synchronization status, the RTCM
message type being received, a quality indicator for message reception, and age
of correction. the response is output in the format:
$PASHS,NME,TCM,d1,d2,d3,d4,f5,d6,d7*hh
Table 8.48 outlines the response message.
