1. Run "head /dev/urandom"
2. Enter some lowercase characters
3. WTF :confused:

Oh I see, a terminal reset fixes it. Guess it's normal then.

normal. it is supposed to be that way and any good tty/pty implementation is like that. type "reset".
some chars ought to trigger different modi.

Yeah, what you're seeing with urandom is just a stream of random 8-bit characters vomiting out on the terminal, which then tries to interpret the characters as output. Since VT100/ANSI/etc all depend on several ways to encode controls, there's a likely chance that random characters coming from urandom will trigger an escape code sequence that causes a mode-change of some sort. Hence, you get the symptoms of the funky terminal. :)

If you stare at that posting long enough, there's no secret message!
