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 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
       -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 cer
	      tain,  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  sys
	      tems, the allowable range is from 0 (no repeat) to 50 cps.

       -d delay
	      Change  the  delay  to delay milliseconds.  For Intel-based sys
	      tems, 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.

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@math.uio.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.
