CKSUM is a two-hex character checksum
as defined in the NMEA specification . Use
of checksums is required on all input
messages.

Each message is terminated by using
Carriage Return (CR) Line Feed (LF) which
is \r\n which is hex 0D 0A. Because \r\n are

Set Serial Port
This command message is used to set the
protocol (SiRF Binary or NMEA) and/or the
communication parameters (baud , data bits,
stop bits, parity). Generally, this command is
used to switch the module back to SiRF
Binary protocol mode where a more

Description
extensive command message set is
available. When a valid message is received,
the parameters are stored in battery-backed
SRAM and then the Evaluation Unit restarts
using the saved parameters.
