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[:at:]math.uio[:dot:]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.
