NAME
     led - SPARC LED driver

SYNOPSIS
     led0 at mainbus0                               (sun4)
     led0 at obio0                                  (sun4m: 4/600)

DESCRIPTION
     The led driver provides a indicator of load average based on blinking of
     the LEDs on some systems.  The pattern takes one second per whole number
     of load average to repeat.  The LED must be explicitly enabled with the
     sysctl(3) variable machdep.led_blink.

SEE ALSO
     sysctl(3), sysctl(8)

HISTORY
     OpenBSD support for the led first appeared in OpenBSD 2.3.
