Old Watching Program?

[notes at acf3.UUCP]

	A while back, around 1984 or early 1985, a program was posted
to net.sources that allowed someone to 'watch' or spy on another 
terminal being used.  It echoed both the input and output to/from
a person's tty.  It dealt with clists (it wasn't a shell script).
Does anyone have a copy of it around, or know where I can get it?
It would be very useful to (1) monitor terminals we have that act
as group consoles, and (2) we have had some "problem" users, and
sometimes need to see what they are doing.  
	This may not be the right newsgroup, but then again, it's
not something that every user should have access to (please don't
send flames!)  This was on a 4.2bsd machine.

	Please e-mail me the responses if you wish.  Thanks.
