I use both Redhat Linux and FreeBSD.  On both of these systems, it'll 
use the file called /usr/local/share/tn5250/XTerm  If I recall correctly,
you're using SuSE...  unfortunately, I have no experience with that
version, so I dont know how to help you!

Perhaps someone else on this mailing list uses the same version of Linux
that you do, and could help you out?

I wish I had a better answer for you...

The xt5250 script sets the directory for the XTerm file by setting the
XUSERFILESEARCHPATH enviornment variable.  You might try bringing up
the /usr/local/bin/xt5250 file in your favorite text editor, and taking
a look at what it does.

If you can't get that to work, you might also try copying
/usr/local/share/tn5250/XTerm to your ~/.Xdefaults file.  That'll allow
you to make the changes on a per-user basis instead of for the whole
system.  (Or at least it does on my computer)

You should also check your termcap/terminfo settings if you're not 
using the ones that were included in the tn5250 distribution.  Many
termcap/terminfo setups only define F1-F20.   You could be experiencing
something similar to this.

Check what your XTerm file is sending, and set your termcap or terminfo
(whichever your system uses) to match.


Another suggestion might be to try using the gtk-5250 version of the
emulator from the gnome-5250 distribution.  This will require you to
install version 0.15.9 of tn5250, and then install gnome-5250 (along
with whatever other dependencies it has... perhaps glib and gtk+?)

Using this will completely circumvent the keyboard mapping :)
Unfortunately, this version is still in development, and not all of its
features work.

Good luck!
