<ClkOffset>

Clock offset of the receiver in Hz, Use 0 for last saved value if available. If
this is unavailable, a default value of 75000 for GSP1, 95000 for GSP 1/LX
will be used.

C). Set DGPS Port ID: 102 Set PORT B parameters for DGPS input
This command is used to control Serial Port B that is an input only serial port used to receive
RTCM differential corrections.
Differential receivers may output corrections using different communication parameters.
The default communication parameters for PORT B are 9600Baud, 8data bits, 0 stop bits, and no
parity. If a DGPS receiver is used which has different communication parameters, use this
command to allow the receiver to correctly decode the data. When a valid message is received,
the parameters will be stored in battery backed SRAM and then the receiver will restart using the
saved parameters.
