Another hardware related question:

Prior to using Xsun the some keys on my IPX's keyboard would not generate
the desired effect (IE arrow keys did not work).  At the time I was
advised that this had to do with the 'sun' terminal type and that running
X would solve this problem. Now that I am using Xsun many of these
problems have been resolved, I still don't have left and right arrow keys,
(This makes text editing interesting) How can I use xmodmap to solve this
problem?
-Thanks
