-From: faith@cs.unc.edu (Rik Faith)
-Subject: User mode keyboard rate changer
-Date: 27 Apr 92 13:44:26 GMT
-
-I put together this program, called kbdrate.c, which will reset the keyboard
-repeat rate and delay in user mode. The program must have read/write
-access to /dev/port, so if /dev/port is only read/writeable by group port,
-then kbdrate must run setgid to group port (for example).
-
-The "rate" is the rate in characters per second
-
-The "delay" is the amount of time the key must remain depressed before it
-will start to repeat.
-
-Usage examples:
-
-kbdrate set rate to IBM default (10.9 cps, 250ms delay)
-kbdrate -r 30.0 set rate to 30 cps and delay to 250ms
-kbdrate -r 20.0 -s set rate to 20 cps (delay 250ms) -- don't print message
-kbdrate -r 0 -d 0 set rate to 2.0 cps and delay to 250 ms
-
-I find it useful to put kbdrate in my /etc/rc file so that the keyboard
-rate is set to something that I find comfortable at boot time. This sure
-beats rebuilding the kernel!

- kbdrate.c -- Set keyboard typematic rate (and delay)
- Created: Thu Apr 23 12:24:30 1992
- Author: Rickard E. Faith, faith@cs.unc.edu
-
- Copyright 1992 Rickard E. Faith. Distributed under the GPL.
- This program comes with ABSOLUTELY NO WARRANTY.
- Usage: kbdrate [-r rate] [-d delay] [-s]
- Rate can range from 2.0 to 30.0 (units are characters per second)
- Delay can range from 250 to 1000 (units are milliseconds)
- -s suppressed message
- Compiles under gcc 2.1 for Linux (tested with the pre-0.96 kernel)
-
- Wed Jun 22 21:35:43 1994, faith@cs.unc.edu:
- Changed valid_rates per suggestion by Andries.Brouwer@cwi.nl.
- Wed Jun 22 22:18:29 1994, faith@cs.unc.edu:
- Added patch for AUSTIN notebooks from John Bowman
- (bowman@hagar.ph.utexas.edu)
-
- Linux/68k modifications by Roman Hodek
- (Roman.Hodek@informatik.uni-erlangen.de):
-
- Reading/writing the Intel I/O ports via /dev/port is not the
- English way... Such hardware dependant stuff can never work on
- other architectures.
-
- Linux/68k has an new ioctl for setting the keyboard repeat rate
- and delay. Both values are counted in msecs, the kernel will do
- any rounding to values possible with the underlying hardware.
-
- kbdrate now first tries if the KDKBDREP ioctl is available. If it
- is, it is used, else the old method is applied.
-
- 1999-02-22 Arkadiusz Mi¶kiewicz <misiek@misiek.eu.org>
- - added Native Language Support
-
- 1999-03-17
- Linux/SPARC modifications by Jeffrey Connell <ankh@canuck.gen.nz>:
- It seems that the KDKBDREP ioctl is not available on this platform.
- However, Linux/SPARC has its own ioctl for this, with yet another
- different measurement system. Thus, try for KIOCSRATE, too.
