getty hangup

[Vernon Schryver]

Does anyone other than me consider that the fact that getty in V/386 3.0e
appears to not have been compiled with '-DHANGUP' a bug?

When getty is not compiled with -DHANGUP (or equivalently hacked), at the
end of a session you are offered a new 'login prompt'.  When compiled with
-DHANGUP, getty momentarily forces DTR false by setting the 'baud rate'
to 0 before starting.  This closes a small security hole.  If this is
undesirable, the -h command line flag (in inittab) can override it, giving
the current Microport 3.0e behavior.

When getty is not compiled with -DHANGUP, you have no option.  It also
fails to behave as the getty(1m) man-page claims.

If getty were compiled with HANGUP, it might be a little messier to use
in 'permissive' installations, but those of us who know the world is out
to get us could find a little comfort.  (Yes, running getty with '-t 60'
is even more comforting.)

Another reason for this feature is that some modems can be fooled into thinking
dial tone is carrier.  Having getty hang up helps a little.

If uport used such a good getty, it's phone modems might not be as busy.

Such a getty would be more compatible with systems sold by Big Workstation
Vendors.
