Cat-ting binary files to the console

[Benjamin Pharr <benpharr@freedom2000net.com>]

Every once in a while I slip up at cat a binary file to the console. (Or 
just forget to give mkisofs the -o flag.)  This causes the console to use 
WEIRD characters, just plain gibberish.  Is there any way to get rid of 
this without rebooting?  Thanks!
