A PuTTY session emulating 'scoansi' on a PC works fine,
as does PTerm doing 'scoansi', but either set as vt100 doesn't
work, so I'd guess that the app is hardcoded to use scoansi
codes, not proper termcap stuff, or it's just not picking them
up because whatever it uses to determine termtype isn't
getting it from the terminal emulator.

Once I get a shell on the SCO box that isn't only able to run the app,
so I can test and set $term, I'll be able to do that.  In the mean
time, I'm wondering if I can use screen to do some magic in the same
way that I did 12 years ago with the old AWA box and SunOS 4.
I just can't remember how that was done with screen.

The client doesn't mind if the procedure isn't automagic (although I
can automate screen startup etc in .login, for example) but they do
want it to work :)
