<Z> Z coordinate position
INT32
<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
is used.

<chnlCount> Number of channels to use.1-12. If your CPU throughput is not high enough,
you could decrease needed throughput by reducing the number of active
channels

C.) Set DGPS Port ID:102 Set PORT B parameters for DGPS input
This command is used to control Serial Port B, an input serial only port used to receive RTCM
differential corrections. Differential receivers may output corrections using different communication
parameters. The default communication parameters for PORT B are set for 9600 Baud, 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 decode data correctly. When a valid message is received, the
parameters are stored in a battery backed SRAM. Resulting, GPS receiver using the saved
Parameters for restart.
