cu(1) and CSRG line
I have reworked cu(1) a bit.  Two changes.  First, the "dir" or telephone
number now goes after the options, not before.  Second, there is a -d flag
which means "don't hangup the line when I ~.";  without the -d option, it
hangs up on termination.  Old shellfiles will have to be changed, and those
people who use things other than cu itself on outgoing lines will have to
remember -d if they want the line to stay connected.  Sorry, there is no
easy way to set things up to permit deciding this at ~. time.

As a consequence of the above, the switch-flipping nonsense for using the
CSRG line is obsolete.  I have changed the strapping option within the
Gandalf to work properly with the cu mods.  To connect to CSRG, the
following now suffices:

	cu -l /dev/tty39 -s 9600 dir

When you do this, you should see "Connected" and then a few seconds later
Dmitri should speak up.  If cu refuses on grounds like "tty access", it
probably means someone else is using the line.  Of course, if you want
to ~. out and then go back in (say at some other speed), you'll need -d.
