See reader questions & answers on this topic! - Help others by sharing your knowledge This is from John Milton's HwNotes series #1. 0 RED: This is the "user LED". It can be turned on and off with the syslocal(2) call. It is not used by any existing applications. 1 GREEN: This is the one most people get wrong. This LED toggles every time there is a process context change, and is cleared on the whole second. 2 YELLOW: This is the idle LED. When it is on, there are no processes in the ready to run state. 3 RED: Heart beat LED. This is toggled on the whole second. This and other interesting information is available in the HwNote series 1-15 that are archived on OSU. User Contributions:Top Document: comp.sys.3b1 FAQ part2 Previous Document: 8.0.
