the barometric pressure altimeter setting provided in fields 1 and 3 of the
transmitted $WIMDA sentence.
Fields <3> and<4> of the $PAMTC,ALT,SET command define how to use the
altitude setting provided in field <2>.
All of the parameters of the $PAMTC,ALT,SET command are stored in
nonvolatile EEPROM memory within the LB150, and so remain programmed
even after cycling power. If any of the fields <2>, <3>, or <4> are null fields, the
corresponding stored value will remain unchanged.
The $PAMTC,ALT,Q command is used to query the values of the parameters
currently programmed into the LB150. The unit will reply with
$PAMTR,ALT,a,b,c
where a, b, and c correspond to fields <2>, <3>, and <4>, respectively, in the
$PAMTC,ALT,SET command.
