Where fields <1> through <9> contain the data from the weather station
instrument's nonvolatile EEPROM, as defined in the "Q", Query Command.
Upon successful completion the weather station instrument will reply with:
$PAMTR,COMP,PASS,
<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>*hh<CR><LF>
Or, upon failure it will reply with:
$PAMTR,COMP,FAILx,
<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>*hh<CR><LF>
Where x indicates the type of failure, 1 = Timeout, 2 = Tilt Error, or 3 = Other Error.
Timeout errors: 5 minute timeout occurred before successful completion or more than
30 seconds was taken to turn thru 45 degrees. Other Errors: reversing the direction of
the turn for more than 45 degrees, for example. The user compass calibration
procedure can be aborted by purposely causing one of the above errors. For example,
stopping the turn will cause an error within 30 seconds, or reversing the direction of
the turn will cause an error even faster.
