kbdrate - reset the keyboard repeat rate and delay time
kbdrate [ -s ] [ -r rate ] [ -d delay ]
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.
-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 --version
Display a version number and exit.
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.
