yes, you're right.. and ESC(B to return to regular display mode..

that's precisely what I am running..

not bad at all with the font I normally use (terminus-12)

I tried smaller fonts but they don't seem to have all the box drawing
characters - in any case the results were not quite as good as with

don't tell me.. I run debian sarge (stable) and try as I may I was never
able to install from source the "debian way". So I had to go through a
lot of contortions to install not just xterm but also recent versions of
screen, elinks, etc. without breaking my system.. hopefully..

I ran it on a 256-color xterm.. not sure whether that helps, though..

.. easiest for someone that has a degree of familiarity with dos. I'm
sure installing dosemu is no big deal on a debian box.. presumably a
simple apt-get install would do it.. but then, I would have to
initialize some form of dos file system.. import the .ans files.. not
easy when you have zero experience with dos.. :-)
