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 the current 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.


 

OPTIONS


       -F     This is the default. Only change the VT flags (and their setting
              may be reflected by the keyboard leds).

       -D     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.

       -L     Do 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.

       -num +num
              Clear or set NumLock.  (At present, the NumLock  setting  influ-
              ences  the  interpretation of keypad keys.  Pressing the NumLock
              key complements the NumLock setting.)

       -caps +caps
              Clear or set CapsLock.  (At present, the CapsLock  setting  com-
              plements  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.)


 

EXAMPLE


       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


 

BUGS


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