Query Commands
The query commands will output a single raw data message type once. The general
format of the query commands is:
$PASHQ,s,c
where s is the 3 character string that denotes the raw data message type, and c is the
serial port to which the message will be output. The serial port field is optional. If the
query is sent with the port field left empty, then the response will be sent to the
current port. If the port field contains a valid port (A-D), then the response will be
output to that port. For example, the query:
$PASHQ,PBN <enter>
will output a single PBEN message to the current port. The command:
$PASHQ,MBN,C <enter>
will output a single set of MBEN message to port C. It is not possible to change the
format (ASCII or Binary) of the response with a query command. If the format of the
port is ASCII, the response will be in ASCII, unless the ASCII format is not available
for that message type. In this case, the receiver will send only the header of the raw
data message.
There are no ACK command acknowledgments for queries. If the query has been
enter properly, and the data is available (for example, MBEN is not available unless
the receiver is tracking enough satellites above the elevation mask), then the
acknowledgment will be the data response message.
Table 6.58 on page 124 lists the available raw data available, the associated 3
character string used in the commands, and the format that is available for each data
type.
