Send these commands directly to the receiver or transmitter.

Send newline (linefeed) (ASCII 0x0A) after all commands to make them take effect.

Sending messages not listed may have unpleasant consequences including bricking your unit.

These commands should not be sent in NMEA sentence format except as noted.
