The X window system provides terminal emulation for a VT102 and
a tektronix 4015.  There are two problems.  First, I don't know
anything about a tek 4015; it seems NOT to be a standard (e.g.,
4012, 4014) tektronix, since it turns the output of the UNIX
"tek" filter into garbage instead of graphics.  Does anyone
have either a modification of "tek" that will support tek 4015
control sequences or a list of tek4015 escape codes?  Second, at least
on the IBM RT-PC (BSD 4.2, IBM 6155 console) on which I have X,
the VT102 emulation breaks for a window with more than 24 lines:
the delete-line code seems not to work (to reproduce, make a window
with more than 24 lines, make sure the environment TERMCAP entry 
has been updated with xsize, and run a vi in the window.  Try to
delete a line somewhere in the middle).
