NAME         top

       kbdrate - reset the keyboard repeat rate and delay time

SYNOPSIS         top

       kbdrate [options...]

DESCRIPTION         top

       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 systems.  These are the IBM defaults. On
       SPARC-based systems it will reset the repeat rate to 5 cps and the
       delay to 200 ms.

OPTIONS         top

       -r, --rate=NUMBER
              Change the keyboard repeat rate to NUMBER 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
              follows: 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=NUMBER
              Change the delay to NUMBER milliseconds.  For Intel-based
              systems, the allowable range is from 250 to 1000 ms, in 250 ms
              steps. For SPARC systems, possible values are between 10 ms
              and 1440 ms, in 10 ms steps.

       -s, --silent
              Silent. No messages are printed.

       -h, --help
              Display a help text.

       -V, --version
              Display a version number and exit.

BUGS         top

       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

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