Sorry, wrong answer; the 4.3BSD version of "telnet" uses (or abuses - it
doesn't follow the protocol, but I'll let those who care one way or the
other argue the point) the "terminal type" option to "telnet" to set
TERM on the remote machine.  Said version is the basis of the one in
4.x; I don't know if it's in 3.x or not.

(Not that it matters, since they probably want the label for either
one....)

Well, two problems with that:

	1) pseudo-ttys *do* have names that don't contain "ttyp", like
	   "ttyq0", "ttyq1", "ttyq1", etc.

	2) TERM is "sun-cmd", not "sun", in a "cmdtool" window.

Both fixable, of course, with different patterns in the "case"
construct.
