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 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	 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.

       -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@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.
