Getty already runs in, or attached to, a window.

That was the old CAPCTRL for version 3.0 of the opsys.  The newer CAPCTRL
is missing this feature.  Though, it is possible to do some nice things
by junking the phone manager and plugging in your own daemon to listen
to the shifted function keys (check windows(7)).

Yes, there's a nice utility available from "the store" called windy that
plays with the windows in nice ways for you.  If you do something like:

	windy -b csh

you'll be put into a new shell in a new window that is running in the
background with regards to the previous shell.  So if you hit Suspd
to get the windows menu, the new shell will have an entry of its own.

I've changed my passwd entry so when I login I go direct to the c-shell.
The tail end of my .login file looks something like this:

	windy -n 'login shell'		# instead of "unknown contents"
	windy -b csh			# so I have a shell to come back to

windy will also let you call up the ua and tear it down again cleanly,
without logging out.

It kinda looks like whoever put the phone manager or whatever together didn't
know about run states.  It appears that once you have your inittab set up
that the only thing they change is to add and delete leading colons to enable
and disable gettys on selected ports.  This is apparently to get the ports
to work bi-directionally.  I have no idea why they didn't use run states,
maybe someone else has a clue.

This is System V, not BSD, that's the way it works.  The -e flag means
print info on all processes, not print the environment as it does with
BSD.

You can buy an ethernet board for the 3B1 for about $700, and the drivers
to make it go are about $300.  I talked to one of the more knowledgeable
folks at one of the software support numbers a few weeks ago and was told
that the software includes "all of the Berkeley 'r' commands", and supposedly
a complete sockets implementation.  I didn't think to ask him which BSD
version they were from, or if the software would fly without the board.

I doubt it, but it would be nice.
