kbdrate

KBDRATE(8)						     Linux Programmer's Manual							KBDRATE(8)

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  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
	      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.

       -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.
