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. +.SH FILES +.I /etc/rc.local +.br +.I /dev/port |
