How do I kill it? I cannot get at the > scroll-lock key from here. I'd say ignore it till you can have a look at the console yourself. There's probably a way to unlock the vty through an ioctl(), if you really want that process killed. My best guess would be to use KDSKBSTATE and turn off the scroll-lock LED, but you'll end up with a confused console, and possibly a panic (manually turning off SLK looks like it unlocks the console, but doesn't clean up the scroll-back history buffer). -Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
