;;; Commentary:
;; Uses the Emacs 19 terminal initialization features --- won't work with 18.
;; Rewritten for Emacs 19 by jimb, January 1992
;; Cleaned up for new terminal package conventions by esr, March 1993
;; Should work well for Televideo TVI 925 although it's overkill.
;;
;; The Wyse50 is ergonomically wonderful, but its escape-sequence design sucks
;; rocks. The left-arrow key emits a backspace (!) and the down-arrow a line
;; feed (!!). Thus, you have to unbind some commonly-used Emacs keys to
;; enable the arrows.

;;; Miscellaneous hacks
;;; This is an ugly hack for a nasty problem:
;;; Wyse 50 takes one character cell to store video attributes (which seems to
;;; explain width 79 rather than 80, column 1 is not used!!!).
;;; On killing (C-x C-c) the end inverse code (on column 1 of line 24)
;;; of the mode line is overwritten AFTER all the y-or-n questions.
;;; This causes the attribute to remain in effect until the mode line has
;;; scrolled of the screen. Suspending (C-z) does not cause this problem.
;;; On such terminals, Emacs should sacrifice the first and last character of
;;; each mode line, rather than a whole screen column!
