Egad! Back in the day all of the /dev/tty entries were world writable.
I used to troll CMU CS Rogue players (when I wasn't playing) from time to
time by sending a string to their tty that grabbed the cursor, moved it to
where the messages appeared (upper left corner?) and typing "The dangling
modifier struck!"
That's all it did. I got a lot of pleasure when I overheard two faculty
members comparing notes on their experiences with the dangling modifier.
Best,

I loved talk when CS was running BSD on a VAX. You
could see who was on
and talk them. Very handy and it was sort of social.
It's crazy how things were back then, open ports listening for all sorts
of things. I think we were pretty unaware of how nasty the internet would
get.

As for the motivation -- it was simple. UCB is

machine room on the second
floor
of Cory Hall. Somebody was usually in the office
most nights, but not
everyone. We all had modems and terminals at home, but only one phone
line. We had 3 Vaxes in the CAD group, plus my Array Processor. So I
wanted to be able to ask someone like Peter or TQ to reset the AP for me
if
I hosed it when I was working from home when I
was debugging it. Plus
the obvious social aspects -- "hey you want go get a Pizza/Beer etc..."
But since we might be working on a different system, Kipps' hack was
useless.
