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 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 keyboard 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 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  keypad  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  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.
