23 ;;; Commentary:
25 ;; Handles all VT100 clones, including the Apollo terminal. Also handles
26 ;; the VT200 --- its PF- and arrow- keys are different, but all those
27 ;; are really set up by the terminal initialization code, which mines them
28 ;; out of termcap. This package is here to define the keypad comma, dash
29 ;; and period (which aren't in termcap's repertoire) and the function for
30 ;; changing from 80 to 132 columns & vv.
32 ;;; Code:
34 ;; Set up function-key-map entries that termcap and terminfo don't know.
