Writing Set Values to EEPROM
The OBR is provided with a function to write the current setting values to EEPROM.
To do this, transmit the 'y' command. If this is not done, other commands that have been transmitted
previously to the 'y' command will not be written to EEPROM. As a result, they will be erased when
the power is turned off and the settings specified by these commands will not be valid the next time
the power is turned on. However, the following commands can not be used to write a setting value to
EEPROM.
One period of buzzer activation/LED ON Command : L
