;;; Commentary:
|

|
|
;; Uses the Emacs 19 terminal initialization features --- won't work with 18.
|
|
|
|
;; Handles all VT100 clones, including the Apollo terminal. Also handles
|
|
;; the VT200 --- its PF- and arrow- keys are different, but all those
|
|
;; are really set up by the terminal initialization code, which mines them
|
|
;; out of termcap. This package is here to define the keypad comma, dash
|
|
;; and period (which aren't in termcap's repertoire) and the function for
|
|
;; changing from 80 to 132 columns & vv.
|
|
|
|
;;; Code:
|
|
|
|
;; Set up function-key-map entries that termcap and terminfo don't know.
