$PASHQ,POS,x
The associated query command is $PASHQ,POS,x where x is the optional output
port.
$PASHR,POS
The response is a message containing information on the most recently computed
position. This response message is in the form:
$PASHR,POS,d1,d2,m1,m2,c1,m3,c2,f1,f2,f3,f4,f5,f6,f7,f8,f9,s*cc
Table 6.75 defines the POS response structure.
