If I don't then the tn5250 mailing list probably will (which I'm 
cc'ing).  Subscribing to the tn5250 mailing list is easy.  Go to:

http://lists.midrange.com/mailman/listinfo/linux5250

(Note to self:  the mailing list isn't mentioned on the HOWTO.  I should 
remedy that along with a few other mistakes I've found.  Anyone else 
know something that is missing from the HOWTO?)

Press Control-q

Are you running tn5250 from the console?  If so, I think you need to use 
the loadkeys command to set up the keymap correctly.  Before running 
tn5250 type 'loadkeys us5250.map'.  If you are using the xt5250 script 
to start tn5250 in X, then all the function keys should be set up 
correctly for you already.

$PREFIX is the installation prefix given when you ran ./configure in the 
tn5250 main directory before compiling.  This defaults to /usr/local. 
So if you didn't give a --prefix argument to ./configure, the global 
parameters would be stored in /usr/local/etc.  This can be further 
overridden using the --sysconfdir argument to ./configure.  For example, 
I usually run configure like this:

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var/lib/tn5250

(that should be all one line but is broken into two by the mailer)  This 
puts the program, libraries, man pages, and shared program data under 
/usr, config files in /etc, and state stuff (which tn5250 doesn't have 
any of) in /var/lib/tn5250.
