The following outlines the serial commands input into the module for
configuration. By default, the commands are input at 9,600bps, 8 data bits, no
parity, and 1 stop bit.
All fields in all proprietary NMEA messages are required; none are optional. All
NMEA messages are comma delimited.
The table below outlines the message identifiers supported by the module.

Message Identifier consisting of three numeric
characters. Input messages begin at MID 100.
Message specific data.
CKSUM is a two-hex character checksum as
defined in the NMEA specification, NMEA-0183
Standard For Interfacing Marine Electronic Devices.
Checksums are required on all input messages.
Each message must be terminated using Carriage
Return (CR) Line Feed (LF) (\r\n, 0x0D0A) to cause
the receiver to process the input message. They are
not printable ASCII characters, so are omitted from
the examples.
