<Eric> I feel bad when handshaking with PuTTY. It supports so
many features. "I can tell you what sort of client I am, would
you like to know?" "Nope." "Well, in that case, let me just
tell you my screen dimensions." "No thanks." "Do you... uh...
want to support environment variables? I got some variables."
"... no." "Well, I guess it's echo off and raw mode, then."
