NAME
       kbdrate - reset the keyboard repeat rate and delay time

SYNOPSIS
       kbdrate [options...]

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 re‐
       set the repeat rate to 5 cps and the delay to 200 ms.

OPTIONS
       -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
       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	for‐
       mer usually works on an m68k/i386 machine, the latter for SPARC.)  When these ioctls fail an ioport interface.
