More on 7/8 bits at login

Yes, it was fixed in System V; there's not really any such thing as "raw
mode".

More to the point, there's no notion that "non-raw mode" means "7 bit
characters only" (that notion is even somewhat gone in 4.3BSD, given
PASS8, and will probably be completely gone in a future release). 

By the time "login" is running, the system is (generally) doing
erase/kill processing, XON/XOFF processing, and interrupt character
processing (unless you've set up "/etc/gettytab" really strangely);
however, there is NO guarantee that either the hardware or the software
is stripping characters to 7 bits (unless you set "/etc/gettytab" up to
do that - but the guy *doesn't* want it to do that, so he specifically
wants to set it up *not* to do that).
