Okay. These sound okay. Your logical terminal should go out 4.0 and
also 5.0. 5.0 is used to find out if stdin/out/err is the "controlling"
terminal.

So in your case /dev/tty0 should look like stdout. If you do
`ls >/dev/tty0` it should print. If it doesn't, try it as a super-user.
It may be that something isn't setting the protection correctly.
