Finding Passwords

[Barry Shein]

Wouldn't an uncatchable (except by a root process) SIGTSTOP character
solve a lot of this relatively harmlessly? The only real problem with
such a thing (that comes up commonly) is the ability to put the
terminal back into line mode when the process is suspended (e.g. full
screen applications.)

Or even a character similar to the TOPS-20 ^T command which printed a
line on the screen about session status.

That way you could type ^T or whatever it is and it might echo:

	/bin/login (PID=2833) running as UID=0

And, again, ^xyz couldn't be trapped.

I would opt for BREAK soas not to lose another control char. And, even
if you have a noisy line sending some breaks at worst you have to
suffer a few unwanted messages to your screen.

Heck, something like this could even be otherwise useful.
