NAME

6       kbdrate - reset the keyboard repeat rate and delay time
7

SYNOPSIS

9       kbdrate [options...]
10

DESCRIPTION

12       kbdrate  is used to change the keyboard repeat rate and delay time. The
13       delay is the amount of time that a key must be depressed before it will
14       start to repeat.
15
16       Using  kbdrate  without  any options will reset the repeat rate to 10.9
17       characters per second (cps) and the delay to 250 milliseconds (ms)  for
18       Intel-  and  M68K-based systems.  These are the IBM defaults. On SPARC-
19       based systems it will reset the repeat rate to 20 cps and the delay  to
20       200 ms.

OPTIONS

24       -r, --rate=NUMBER
25              Change  the  keyboard repeat rate to NUMBER cps. For Intel-based
26              systems, the allowable range is from 2.0 to 30.0 cps.  Only cer‐
27              tain,  specific values are possible, and the program will select
28              the nearest possible value to the one  specified.  The  possible
29              values  are  given,  in  characters per second, as follows: 2.0,
30              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,
31              6.7,  7.5,  8.0,  8.6,  9.2, 10.0, 10.9, 12.0, 13.3, 15.0, 16.0,
32              17.1, 18.5, 20.0, 21.8, 24.0, 26.7, 30.0.  For SPARC-based  sys‐
33              tems, the allowable range is from 0 (no repeat) to 50 cps.
34
35       -d, --delay=NUMBER
36              Change  the  delay to NUMBER milliseconds.  For Intel-based sys‐
37              tems, the allowable range is from 250 to  1000  ms,  in  250  ms
38              steps.  For SPARC systems, possible values are between 10 ms and
39              1440 ms, in 10 ms steps.
40
41       -s, --silent
42              Silent. No messages are printed.
43
44       -h, --help
45              Display a help text.
46
47       -V, --version
48              Display a version number and exit.

BUGS

51       Not all keyboards support all rates.
52
53       Not all keyboards have the rates mapped in the same way.
54
55       Setting the repeat rate on the Gateway AnyKey keyboard does  not  work.
56       If  someone  with  a  Gateway  figures out how to program the keyboard,
57       please send mail to util-linux@math.uio.no.
58
59       All this is very architecture dependent.  Nowadays kbdrate first  tries
60       the  KDKBDREP  and  KIOCSRATE  ioctls.  (The former usually works on an
61       m68k/i386 machine, the latter for SPARC.)  When these  ioctls  fail  an
62       ioport interface.
