Save settings to flash (SV)

The SV command is used to save the current settings into the flash. The red light will light up during the ``save'' operation. The saved parameters will be loaded each time the Cricket powers up or when the ``P LD'' command is sent to the Cricket unit.

Note: The flash is erased each time the Cricket is reprogrammed with new software. Non-default configuration parameters that were previously saved will not be retained across reprogramming actions.
