This article is from a FAQ concerning SCO operating systems. While some of the information may be applicable to any OS, or any Unix or Linux OS, it may be specific to SCO Xenix, Open There is lots of Linux, Mac OS X and general Unix info elsewhere on this site: Search this site is the best way to find anything.
If this message stair-steps across your screen and you can't do a ^D, the file /etc/ioctl.syscon has become corrupt. Go into single- user mode by typing the root password followed by ^J instead of a carriage return. Use stty sane^J to restore your console to more normal operation. Remove /etc/ioctl.syscon, and reboot by running /etc/reboot. The system will complain that /etc/ioctl.syscon is missing and will rebuild it for you.
The usual cause for this file becoming corrupt was that the system was shut down from a terminal other than the console, and this file now contains the stty settings for that terminal (which are probably not correct for the console).
Also: /dev/console, /dev/syscon, /dev/systty should all be device 3,1. Use "ln -f" if one or more is bad.
ln -f console syscon
