100 – SetSerialPort
This command message is used to set the protocol (SiRF binary or NMEA)
and/or the communication parameters (baud rate). Generally, this
command is used to switch the module back to SiRF binary protocol mode
where a more extensive command message set is available. When a valid
message is received, the parameters are stored in battery-backed SRAM
and the receiver restarts using the saved parameters.
Figure 20 below contains the values for the following example:

For details on the SiRF binary protocol, please refer to SiRF’s Binary
Protocol Reference Manual.
1. SiRF protocol is only valid for 8 data bits, 1 stop bit and no parity.
2. Default settings are NMEA protocol using 9,600 baud, 8 data bits, 2 stop bits and no
