NAME
       setleds - set the keyboard leds

SYNOPSIS
       setleds [-v] [-L] [-D] [-F] [{+|-}num] [{+|-}caps] [{+|-}scroll]

DESCRIPTION
       Setleds	reports	 and changes the led flag settings of a VT (namely NumLock, CapsLock and ScrollLock).  Without argu‐
       ments, setleds prints the current settings.  With arguments, it sets or clears the indicated flags  (and	 leaves	 the
       others unchanged).  The settings before and after the change are reported if the -v flag is given.

       The led flag settings are specific for each VT (and the VT corresponding to stdin is used).

       By default (or with option -F), setleds will only change the VT flags (and their setting may be reflected by the key‐
       board leds).

       With option -D, setleds will change both the VT flags and their default settings (so that a subsequent reset will not
       undo the change).  This might be useful for people who always want to have numlock set.

       With option -L, setleds will not touch the VT flags, but only change the leds.  From this moment on, the leds will no
       longer  reflect	the VT flags (but display whatever is put into them).  The command setleds -L (without further argu‐
       ments) will restore the situation in which the leds reflect the VT flags.

       One might use setleds in /etc/rc to define the initial and default state of NumLock, e.g. by
	    INITTY=/dev/tty[1-8]
	    for tty in $INITTY; do
		 setleds -D +num < $tty
	    done

OPTIONS
       -num +num
	      Clear or set NumLock.  (At present, the NumLock setting influences the interpretation of keypad keys.   Press‐
	      ing the NumLock key complements the NumLock setting.)

       -caps +caps
	      Clear  or	 set CapsLock.	(At present, the CapsLock setting complements the Shift key when applied to letters.
	      Pressing the CapsLock key complements the CapsLock setting.)

       -scroll +scroll
	      Clear or set ScrollLock.	(At present, pressing the ScrollLock key (or ^S/^Q) stops/starts console output.)

BUGS
       In keyboard application mode the NumLock key does not influence the NumLock flag setting.
