It sounds like your Linux system is running Redhat.  I get lots of 
complaints about that (for instance earlier today ;-). For quite a while
(I'm told it was corrected in Fedora) their package for xterm alters most 
of the key translations, lobotomizing it to look like someone's 
improvement to old xterm.

A quick check on my system shows it producing \EOH and \EOF
(though the correct answer depends on the resource settings of course).

Actually vim can use the termcap/terminfo settings (though I understand it 
has a built-in copy of one of the flavors for "xterm").
