Nmea Transmitted Sentences - Garmin TracPak GPS 30/30 SL Manual

<1> Target sentence description (e.g., PGRMT,
GPGSV, etc.)
<2> Target sentence mode, where:
0 = disable specified sentence
1 = enable specified sentence
2 = disable all output sentences
3 = enable all output sentences (except
GPALM)
The following notes apply to the PGRMO input sentence:
1) If the target sentence mode is '2' (disable all) or '3'
(enable all), the target sentence description is not
checked for validity. In this case, an empty field is
allowed (e.g., $PGRMO,,3), or the mode field may
contain from 1 to 5 characters.
2) If the target sentence mode is '0' (disable) or '1'
(enable), the target sentence description field must
be an identifier for one of the sentences being output
by the GPS 30/30 SL.
3) If either the target sentence mode field or the target
sentence description field is not valid, the PGRMO
sentence will have no effect.
4) $PGRMO, GPALM, 1 will cause the GPS 30/30 SL
to transmit all stored almanac information. All other
NMEA sentence transmission will be temporarily
suspended.
