------------------------------------------------------------------------
A brief synopsis of the problem:

Macsyma graphs in Tektronix windows don't seem to work anymore.


------------------------------------------------------------------------
Please describe the problem in detail (mention any necessary files or
commands that may be involved, on which machine the bug happened, and what
the program did that was wrong):

Pertinent software:
	Standard VS2000 5.5T workstation.
	Standard version of macsyma (/usr/athena/macsyma).
	Bugfix version of xterm (/mit/fixes/vaxbin/xterm).

When a Macsyma graph is requested in a Tektronix window, Macsyma fills the
window with many asterisks, instead of drawing a graph.

The terminal type was set to "tek4014" before entering Macsyma.

------------------------------------------------------------------------
Repeat by (please enter a set of commands which will allow us to 
repeat the bug):

% attach fixes
% /mit/fixes/vaxbin/xterm -t &

[then, in the new xterm:]

% set noglob; eval `tset -s -Q - tek4014`
% macsyma
		.
		.
		.

(c1) exp(-x^2-y^2)*x;

(d1)                          2   2
                           - y - x
                       x %e

(d2) equalscale:false$
(d3) plot3d(d1,x,-2,2,y,-1.5,2.5);

		.
		.
	(wait a long time)
		.
		.

[ * * * * * * Asterisks everywhere * * * * * ]
------------------------------------------------------------------------
Fix (if you know what it is):

Macsyma probably isn't recognizing the terminal type correctly.
