terminal goes funky

[Sven Burgener <svenb@bluewin.ch>]

Silly me accidentally cat'ed a binary file, which caused the terminal 
(tty1) to go all funky.

It seems to display things fine, but just with weird characters instead
of proper ones. Some characters are fine though, like the "GNU" part of
the login prompt. :)

I saw someone undoing a situation as such, but forgot how to do it as I
very seldom get bogged like this.

A reboot would surely fix this, but I dont want to do that. Kill or
HUP'ing the getty doesn't do the job.

Thanks
Sven
