I couldn't find those .. but then the xterm I'm using is out of an
xfree 4.3.0 tree - XTerm(222) per xterm -v. so that may be the reason.

I have a feeling my Tek emulation is not set up properly either: font
is double-spaced .. arrow keys do not work .. even after issuing CTRL+L
some of the previously typed text remains visible and overtyping it
causes non-ascii characters to be displayed etc..

It's rather difficult to figure out how it should behave since I've
never seen it properly set up and there are probably not screen shots
available anywhere .. and in any case since it seems to be nothing more
than a historical curiosity at this point .. I'm not sure I should
bother anybody with this in the first place.

I did play a bit with plotutils and got the examples on the man pages
to work and (same as the tektest samples) the results are quite
striking.

Thanks.
