This dirctory should be located in tn3270 of the distribution.
i.e. we are located  ..... bla bla .../dist3270/tn3270/iris4d

This directory contains those files which were modified, or added, inorder
to get tn3270 to work on my IRIS 4D/70 GT.  They are:

Makefile
README
ioccom.h
map3270
outbound.ed
rex.h
rex.x
telnet.ed
ttold.h
ttycom.h
--------------------------------------
cd to this directory and type:

	make ready-iris4d
	cd ..
	make install

and you should have a working tn3270.

telnet.c was the biggest problem; it relied on a number of special
include files which IRIS computer don't have.  I found them on a BSD
machine; a sun 386i.  The include files were hacked up and not cleaned up
so you will get warning messages about redefining variables.

I have included a map3270 which I like.  For more information on
what the escape sequences mean see appendix A of "4Sight User's
Guide - Terminal and Keyboard data."

Good luck!
