Well, the easiest bit is to get the shift+tab working.  This requires:

"loadkeys /usr/share/tn5250/us5250.map" This loads the kernel keymap
which includes a mapping for shift+tab (as F100), F21, F22, F23 and F24.
(which are not defined by default on Linux)

"export TERM=5250" or "set TERM 5250" (or "set TERM=5250"?) depending on
your shell.  This tells tn5250 and/or terminfo/termcap to interpret the
"F100" string defined in the us5250 map as a backtab.

then run tn5250

This gets shift+tab/backtab working properly.

To get left control mapped to reset, change the following in us5250.map:
keycode  29 = Control
to
keycode  29 = Control_r

I just realized that I missed another important one: Attn/SysReq.

To get that mapped to escape, change:
keycode   1 = Escape
to
keycode   1 = Control_a        Control_c

Not sure how common it is, but on the original 5250 terminal keyboard
the Field Exit key was where the Enter key is on a PC keyboard, and the
Enter key was where the right control key is.  So sometimes it is useful
to do those mappings as well.

These changes can be done by changing:

keycode  28 = Return
to
keycode  28 = Control_k

and

keycode  97 = Control
to
keycode  97 = Return
