+Description:
+ Reverse the blink logic. If set to 0 (default) blink on for
+ delay_on ms, then blink off for delay_off ms, leaving the LED
+ normally off. If set to 1, blink off for delay_off ms, then
+ blink on for delay_on ms, leaving the LED normally on.
+ Setting this value also immediately changes the LED state.
