% NMODE-VAX.SL  Vax-Unix specific loading and modifications for NMODE.
% 
% Author:      William F. Galway
%              University of Utah
% Date:        28 March 1983
% Revised:     5 April 1983
%
% 7-Apr-83 Nancy Kendzierski
%  Added knowledge about hp and 2641 terminal types to table.
% 5-Apr-83 Alan Snyder
%  Revised to be more like the 9836 code: add load-nmode stuff and set-terminal
%  stuff.
%
% This file contains functions to load NMODE and make some final changes to
% customize things for Vax-Unix.  Some modules for NMODE are unimplemented on
% the Vax, thus not loaded for now; these are commented out with a "%*".
