I have a logical problem with doing this, though. It seems backwards. The
terminfo and termcap databases are supposed to be used to tell the
operating system what kind of terminal you're actually using (whether it's
an emulated VT220, or the console on a Linux box). Since you're not
on a 5250 terminal when you're running tn5250, it doesn't really make
sense to tell the operating system that you are. At best, it's a hack,
even if it is a very good hack. tn5250 is designed to translate 5250
display data to ncurses display, and ncurses translates it into display
data appropriate to your local terminal (or local terminal emulator). It
makes sense that the opposite sequence should be used for input data
(local terminal -> ncurses -> 5250).

Of course, your point in a later e-mail about the fact that depressing
some keys on most local terminals won't generate keypress data for ncurses
to use (e.g. the control keys by themselves) is definitely valid, though.

Cheers,
Mick
