uucp VS 4.2 (System V comment)

[Tony L. Hansen]

An interesting point about System V (as distributed) is that it accepts any
of '@', DEL or ^U for erasing the line when you're talking to getty. It only
accepts '#' for character erase, however. All of this is done in raw mode.
If it sees what looks like a NULL character (coming from typing ^@, CR at a
higher line speed, or the break key), it will search for the next line entry
and speed in /etc/gettydefs. I haven't checked System V Release 2 to see if
it has the same properties.

Unfortunately, once you've gotten to the first "Password:" prompt, you are
no longer talking to getty, but instead to login, which does things in
cooked mode rather than in raw mode, so you're back to the old '@' again.
