;;; Commentary:

;; Uses the Emacs 19 terminal initialization features --- won't work with 18.

;;; Code:

(defun terminal-init-AT386 ()
  "Terminal initialization function for AT386."
  (let ((AT386-keypad-map (lookup-key input-decode-map "\e[")))
    ;; The terminal initialization should already have set up some keys
    (if (not (keymapp AT386-keypad-map))
	(error "What?  Your AT386 termcap/terminfo has no keycaps in it"))

    ;; Equivalents of these are set up automatically by termcap/terminfo
    ;;  (define-key AT386-keypad-map "A" [up])
    ;;  (define-key AT386-keypad-map "B" [down])
    ;;  (define-key AT386-keypad-map "C" [right])
    ;;  (define-key AT386-keypad-map "D" [left])

    ;; These would be set up by terminfo, but not termcap
    (define-key AT386-keypad-map "H" [home])
    (define-key AT386-keypad-map "Y" [end])
    (define-key AT386-keypad-map "U" [next])	;; PgDn

    (define-key AT386-keypad-map "@" [insert])	;; Ins key

    ;; These are not normally set up by either
    (define-key AT386-keypad-map "G" [kp-5])	;; Unlabeled center key
    (define-key AT386-keypad-map "S" [kp-subtract])
