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