26 | ;; Uses the Emacs 19 terminal initialization features --- won't work with 18. | |
27 | ||
28 | ;; Handles all VT100 clones, including the Apollo terminal. Also handles | |
29 | ;; the VT200 --- its PF- and arrow- keys are different, but all those | |
30 | ;; are really set up by the terminal initialization code, which mines them | |
31 | ;; out of termcap. This package is here to define the keypad comma, dash | |
32 | ;; and period (which aren't in termcap's repertoire) and the function for | |
33 | ;; changing from 80 to 132 columns & vv. | |
34 | ||
35 | ;;; Code: | |
36 | ||
0e73af29 | 37 | ;; Set up function-key-map entries that termcap and terminfo don't know. |
