       kbdrate - reset the keyboard repeat rate and delay time

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

       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 rate to
       10.9 characters per second (cps) and the delay to 250 mil-
       liseconds  (ms) for Intel- and M68K-based systems (the IBM
       defaults), or on SPARC-based systems, the rate  to  5  cps
       and the delay to 200 ms.

       -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:  0.0  (no  repeat),  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 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.

       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-

       This  has  been  tested  on Intel-, SPARC-, and M68K-based
       machines.  It may not work on other architectures.
