KBDRATE(8)                 Linux Programmer’s Manual                KBDRATE(8)



NAME
       kbdrate - reset the keyboard repeat rate and delay time

SYNOPSIS
       kbdrate [ -s ] [ -r rate ] [ -d delay ]

DESCRIPTION
       kbdrate  is  used  to change the keyboard repeat rate and delay time.  The delay is
       the amount of time that a key must be depressed before it will start to repeat.

       Using kbdrate without any options will reset the repeat rate to 10.9 characters per
       second  (cps) and the delay to 250 milliseconds (ms) for Intel- and M68K-based sys-
       tems.  These are the IBM defaults. On SPARC-based systems it will reset the  repeat
       rate to 20 cps and the delay to 200 ms.


OPTIONS
       -s     Silent.  No messages are printed.

       -r rate
              Change  the keyboard repeat rate to rate cps.   For Intel-based systems, the
              allowable range is from 2.0 to 30.0 cps.  Only certain, specific values  are
              possible,  and the program will select the nearest possible value to the one
              specified.  The possible values are given, in characters per second, as fol-
              lows:  2.0, 2.1, 2.3, 2.5, 2.7, 3.0, 3.3, 3.7, 4.0, 4.3, 4.6, 5.0, 5.5, 6.0,
              6.7, 7.5, 8.0, 8.6, 9.2, 10.0, 10.9, 12.0, 13.3,  15.0,  16.0,  17.1,  18.5,
              20.0,  21.8, 24.0, 26.7, 30.0.  For SPARC-based systems, the allowable range
              is from 0 (no repeat) to 50 cps.

       -d delay
              Change the delay to delay milliseconds.  For Intel-based systems, the allow-
              able  range is from 250 to 1000 ms, in 250 ms steps. For SPARC systems, pos-
              sible values are between 10 ms and 1440 ms, in 10 ms steps.

       -V     Display a version number and exit.

BUGS
       Not all keyboards support all rates.

       Not all keyboards have the rates mapped in the same way.

       Setting the repeat rate on the Gateway AnyKey keyboard does not work.   If  someone
       with  a  Gateway figures out how to program the keyboard, please send mail to util-
       linux AT math.no.

       All this is very architecture dependent.  Nowadays kbdrate first tries the KDKBDREP
       and KIOCSRATE ioctls.  (The former usually works on an m68k machine, the latter for
       SPARC.)  When these ioctls fail an ioport interface as on i386 is assumed.
