I'll second that belief.

Yep, mapping FROM whatever you already have TO IBM 3270.  What the IBM
folks want goes in the opposite direction, and it's just not there.

In my limited experience, a 3270 is virtually useless on a unix
machine unless all you want is a dumb terminal.  The line-oriented
nature of the 3270 just does not lend itself to such applications as
one normally uses in the unix environment.  Not to mention the potential
hassle of EBCDIC/ASCII conversion.  (carets, square brackets, etc.)

Even when unix runs on IBM machines, the terminal of choice is an
ASCII terminal.  Sigh.
