If the input parameter value is 255, the SL869 responds with a message of the form:
$GPTXT,<Telit version string>*<checksum><cr><lf>
3.13.
$PSTMSBASONOFF
This command can be used to toggle the SBAS differential GPS feature on and off. By
default the SBAS feature is off (disabled) whenever the SL869 is reset. When SBAS is on
(enabled), the SL869 searches for SBAS satellites. If the SL869 successfully acquires a
satellite, it obtains and uses differential GPS corrections transmitted by the satellite. The
SBAS PRN appears in the GPGSV messages as specified in the NMEA standard.

$PSTMSBASSAT
This command is used to select the SBAS PRN code to be used for differential operation. By
default the SBAS PRN is automatically selected by the SL869. If an SBAS PRN is selected
but cannot be acquired, the SL869 searches for other SBAS satellites. The SL869 reverts
back to automatic SBAS selection when it is reset or is power cycled.
