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.
Change the keyboard repeat rate to NUMBER 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.
Change the delay to NUMBER 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.

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 firstname.lastname@example.org.
All this is very architecture dependent. Nowadays kbdrate first
tries the KDKBDREP and KIOCSRATE ioctls. (The former usually
works on an m68k/i386 machine, the latter for SPARC.) When these
ioctls fail an ioport interface.
