The $PAMTC,EN,S command causes the contents of the current working copy in RAM
to be saved to EEPROM. The saved settings will then be restored to RAM each time
power is applied to the unit.
The $PAMTC,EN,L command allows the settings to be reloaded from EEPROM to
RAM without cycling power to the unit. This can be used to discard any changes made
to the working copy in RAM, and restore the saved settings as though the unit had been
turned off and then back on again.
The $PAMTC,EN,LD command loads the factory default settings from ROM memory
into RAM memory.
Note that the $PAMTC,ERST command (see separate description) differs from the
$PAMTC,EN,LD command in that $PAMTC,ERST will initialize all of user EEPROM
memory to its factory default settings. This includes settings unrelated to the selection of
transmitted sentences.
The above paragraphs are summarized in the below figure.

The $PAMTC,EN,Q command provides a query function to allow reading the current
settings from the working copy in RAM. The reply to the $PAMTC,EN,Q command is a
series of sentences with the following format:
$PAMTR,EN,<1>,<2>,<3>,<4>,<5>*hh<CR><LF>
where
<1> = Total number of $PAMTR,EN sentences in the reply
<2> = Sentence number
<3> = Sentence ID (GGA, GLL, GSA, GSV, HDG, MDA, MWD, MWVR,
MWVT, RMC, VTG, VWR, VWT, or XDR)
<4> = 0 or 1 (0=disabled, 1=enabled)
