There's another way to do this, that I use in my Debian package
(editing configuration files is not permitted in Policy).  You put the 
Xdefaults file in some file called XTerm, in /usr/share/tn5250/XTerm
for example, then make xt5250 be the following:

----------
#!/bin/sh

XUSERFILESEARCHPATH=/usr/share/tn5250/%N
export XUSERFILESEARCHPATH

xterm -geometry 80X25 -name "xt5250" -bg black -fg white -tn xt5250 +sb -e 
tn5250 "$@"  &
----------

(I've also added "+sb" to disable the scroll bar because it's useless
with tn5250.)

I don't need to be root to run loadkeys on Debian 2.2-ish, kernel
2.2.12, console-tools 0.2.2.

If you don't want TERM to be 5250 for everything else, this /could/ be 

% TERM=5250 tn5250 -u my.ip.address

It is also possible to just specify the /changes/ in the terminfo
file.  For example, I have a terminfo which says:

5250|linux-5250|linux console 5250 terminal,
        kf21=\E[35~, kf22=\E[36~, kf23=\E[37~, kf24=\E[38~,
        use=linux,

and a separate one for my xt5250 which says:

xt5250|xterm-5250|xterm 5250 terminal,
        kf21=\E[35~, kf22=\E[36~, kf23=\E[37~, kf24=\E[38~,
        kcbt=\E[Z,
        use=xterm-xfree86,

Another good example would be:

% xt5250 -y IBM-3477-FC -s EVANSCS1 neptune

which gives me a 132x27 screen when the AS/400 wants it.


It's probably also worth mentioning the "-m" switch somewhere, with a
pointer to the IBM manual at

    http://publib.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/QB3AWC01/G.2

which lists values for the CCSID.  You can also get some idea what
this should be with the command "DSPSYSVAL QCCSID".


Also, if you want to refer to the AS/400 by name instead of IP
address, but it doesn't work, add something like the following line to 
/etc/hosts:

10.1.1.5        neptune.example.com neptune
