Re: New User Requires Help With Keyboard Re-mapping]

tn5250 does not "really" do keyboard mapping.  It relies on your
terminal's capability to do that.

When you run the xt5250 script (which is nothing more than a shell script)
it creates a new xterm, tells the xterm what keyboard settings to use
by directing it to your /usr/local/share/tn5250/XTerm file, and then
runs the tn5250 program.

If you want to run tn5250 instead of xt5250, then you have to do that
manually.   Since TN5250 does not do keyboard mapping, then how you do
it will depend on your terminal!

The Linux console does it using the "loadkeys" command.  You need to
make your keyboard mapping changes in the "us5250.map" or "uk5250.map"
(or whatever is appropriate) and then load it by running "loadkeys
us5250.map"

If you're doing this from X, then you could do it from an xterm.  This
is what xt5250 does.  If you don't want to use xt5250, you could try
doing it manually (thought it's not simple) by doing something like
this:
     1)  Make your own copy of /usr/local/share/tn5250/XTerm:
              cd /usr/local/share/tn5250
              cp XTerm mymap
     2)  Edit your copy, and change the "xt5250" on the top
          line of the file to read "xterm".
     3)  Run xrdb to load your settings:
            xrdb mymap
     4)  Launch a new xterm, using the xterm-5250 terminal type:
            xterm -fg white -bg black -tn xterm-5250
     5)  And in your new xterm, run tn5250:
              tn5250 gec400

If you looked at the xt5250 script, you'd see that it's doing pretty
much the same thing... though it has a few more bells and whistles,
and only affects xt5250 sessions, not all xterms.

If you want to run tn5250 with keyboard mapping in another terminal,
such as the ones included with KDE, or Gnome, then you'd have to figure
out how to do keyboard mapping in THOSE terminals.   I can't help you
with that one, I've never done it.

Again, I strongly recommend that you get xt5250 working instead.  Trying
to do it yourself is the long-way-around.
