That depends.  If I'm using minicom to access a console on the serial
port it depends on whether I tell minicom to hangup when I disconnect (I
don't usually).  This is not my real concern - I'm not too fussed about
whether the session dies or not.  My real concern is whether I can
connect to it afterwards (new session or otherwise).  If I put the
initial console on the serial port, I can't reconnect to that console
after a disconnect.

That works for me, but not for users.  I need to make the system
fool-proof so that users can't lose the ability to connect to their
machine just because they hit the wrong button when leaving screen.
Also, I use a rather more stripped down terminal emulator as I don't
wish to make screen available to users.
