I have a P133/2940/16MB system, and a friend of mine It's a problem with the protocol used to talk to the keyboard, and isn't terribly easy to work around. Basically what happens is that the keyboard controller and the keyboard get out of sync; you can try unplugging and replugging your keyboard, which may clear the problem if it's your keyboard that's confused, and if your keyboard doesn't require a reset from the PC before working (most modern keybpards fit this category). A proper workaround would involve decoupling the keyboard communications stuff from the console driver, and raises nasty issues to do with keeping the keyboard state in sync with the selected VTY. > Dan Walters -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
