recognised.
Description
Use the ID command to set the listener and talker address identifiers. See Section 6.4.4 for
information on listener and talker address identifiers.
From software V7.5.1 the ID command can also be used to modify the Talker ID for the
NMEA 0183 data format (see Section 7.4.30). Please note that the NMEA 0183 data
standard format does not officially support alternative talker IDs and may result in failure to
communicate or interpret data.
