kbdrate \- reset the keyboard repeat rate and delay time
|
|
.SH SYNOPSIS
|
|
.B "kbdrate [ \-s ] [ \-r"
|
|
rate
|
|
.B "] [ \-d"

|
|
.SH DESCRIPTION
|
|
.B 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
|
|
.B 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.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-s
|
|
Silent. No messages are printed.
|
|
.TP
|
|
.BI \-r " rate"
|
|
Change the keyboard repeat rate to
|
|
.I 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.
|
|
.TP
|
|
.BI \-d " delay"
|
|
Change the delay to
|
|
.I 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.

|
.SH BUGS
|
|
Not all keyboards support all rates.
|
|
.PP
|
|
Not all keyboards have the rates mapped in the same way.
|
|
.PP
|
|
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.
|
|
.PP
|
|
All this is very architecture dependent.
|
|
Nowadays
|
|
.B 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.
