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 arguments, setleds prints the current settings.	With arguments, it sets or clears the  indi‐
       cated 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 re‐
       flected by the keyboard leds).

       With option -D, setleds will change both the VT flags and their default settings (so  that  a  subse‐
       quent  reset will not undo the change).	This might be useful for people who always want to have num‐
       lock 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 arguments) 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 key‐
	      pad keys.	 Pressing the NumLock key complements the NumLock setting.)

       -caps +caps
	      Clear or set CapsLock.  (At present, the CapsLock setting complements the Shift key  when	 ap‐
	      plied 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.
