Table 4.23 defines the parameters.
PAR: Query General Receiver Parameters
$PASHQ,PAR,[c1]
This command allows you to query for the current settings of general receiver
parameters, 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.
The response message has a free-form Ashtech proprietary format. This message
does not have a header or message identifier as shown in the following example:
SPDA:5 SPDB:5
GPS:YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
PMD:1 FIX:0 ALT:+00000.00 PDP:40 HDP:04 VDP:04 ERM:6000,6000,6000,6000

Table 4.23. Format of Response for $PASHQ,MEM
Parameter Description Range
h1 Volatile memory test result. The returned value should always be FFF0
h2 Non-volatile memory checksum result. A non-zero result indicates a
checksum failure, and the receiver will re-test this memory sector. In this
case, the third field will show the result of the non-volatile memory re-test.
A non-zero value is registered in this field the first time the receiver is used
Zero / Non-zero
h3 If the second field contains a non-zero value, indicating a failure in the
checksum reading of the non-volatile memory, this field will show the
results of the re-test of that memory sector. If non-volatile memory passes
the re-test, the value in this field must be 8000. If the second field contains
a zero value, indicating a good checksum, this field is ignored
FFFF / 8000
h4 This field must always be zero 0000
h5 ROM checksum result. A zero value indicates the checksum is good 0000
