blink pattern

RC4 Wireless devices use small colored LEDs to indicate various modes of operation.  In addition to indicators simply being on or off, they can blink at different speeds or blink with patterns that indicate a particular setting or parameter value.  For example, an indicator might indicate 1 short blink, or 2 short blinks followed by a pause, or 3 short blinks followed by a pause to indicate different options or selections.
