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 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 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 pro-
       gram the keyboard, please send mail to util-linuxATmath.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.
