depending on
your shell. This tells tn5250 and/or terminfo/termcap to
interpret the
"F100" string defined in the us5250 map as a backtab.

Oh, forgot to add that this requires the terminfo definition for the
5250 terminal, which should be installed when tn5250 is.

And I should have also mentioned that the following two mappings mean
that you have *no* control keys, meaning that control+alt+F# to
change
VTs won't work, and control+Q to exit tn5250 also won't work. Alt +F#
should work to change VTs though, and from there you should be
able to
log in and kill tn5250 (remember that right-control is enter though!)

and 'loadkeys -d' will load the default kernel keymap, allowing
you to
get the standard keymap back.

Is it universal across all the consoles? i.e. once I run loadkeys on
one terminal they are all changed?

Since control-alt to change screens is a staple for the users now, I
may just leave those control keys alone. Control-R for reset is at
least
memorable.

And since it's the field+ and field- I was after most, I'm guessing I
need to change

keycode 74 = KP_Subtract
to
keycode 74 = Control_x
and
keycode 78 = KP_Add
to
keycode 78 = Meta_m

Responding to may own note for the archives more than anything else...
For Ubuntu gutsy...

sudo aptitude install console-data

Add this to the tn5250.map included with tn5250 install (note reversed
from above!)

keycode 78 = Control_x
keycode 74 = Meta_m

then

sudo loadkeys us5250.map
export TERM=5250 #(not TERM=tn5250!)

tn5250 now works as expected until you reboot.
According to the man page install-keymap should make the change
permanent, but it doesn't (see bug#1918463 on launchpad)
<https://bugs.launchpad.net/ubuntu/+source/console-data/+bug/198483>

Note this means that the keypad plus and minus keys are now useless for
regular console use (on all consoles!) until you do

sudo loadkeys -d

I think I understand now why the original programmer made the keypad
plus and minus be field+ and field- on signed fields only - there must
be some custom code in there to capture that, and done that way the
keypad still works as expected in a regular console....

Now I'm off to reproduce this on older Mandrake boxes.

PLEASE NOTE I CREATED AN RPM USING CHECKINSTALL RATHER THAN RPM FROM URPMI SO YOUR RESULTS MAY VARY...

This is a bit of a nasty hack, but by adding these lines to the end of
/usr/lib/kbd/keymaps/i386/qwerty/defkeymap.kmap.gz

you get Shift-Tab, F21 thru 24 and I've decided to try Shift and Keypad Plus as Field+, Shift and Keypad Minus as Field-

keycode 15 = Tab F100$
keycode 78 = KP_Add Control_x$
keycode 74 = KP_Subtract Meta_m$
string F21 = "\033[35~"$
string F22 = "\033[36~"$
string F23 = "\033[37~"$
string F24 = "\033[38~"$
string F100 = "\033[Z"$

I might try this same approach (hacking the default rather than setting a new keymap) on Ubuntu gutsy too.

Hope this helps somebody.

Brian
