- ;; Associate EDT keynames with Emacs terminal function vector names.
- ;;
- ;; To emulate the DEC LK-201 keypad keys on the PC 101 keyboard,
- ;; NumLock must be ON.
- ;;
- ;; The PC keypad keys are mapped to the corresponding DEC LK-201
- ;; keypad keys according to the corresponding physical position on
- ;; the keyboard. Thus, the physical position of the PC keypad key
- ;; determines its function, not the PC keycap name.
- ;;
- ;; There are two LK-201 keypad keys needing special handling: PF1 and
- ;; the keypad comma key.
- ;;
- ;; PF1:
- ;; Most PC software does not see a press of the NumLock key. A TSR
- ;; program distributed with MS-Kermit to support its VT-100 emulation
- ;; solves this problem. The TSR, called GOLD, causes a press of the
- ;; keypad NumLock key to look as if the PC F1 key were pressed. So
- ;; the PC F1 key is mapped here to behave as the PF1 (GOLD) key.
- ;; Then with GOLD loaded, the NumLock key will behave as the GOLD key.
- ;;
- ;; By the way, with GOLD loaded, you can still toggle numlock on/off.
- ;; GOLD binds this to Shift-NumLock.
- ;;
- ;; Keypad Comma:
- ;; There is no physical PC keypad key to correspond to the LK-201
- ;; keypad comma key. So, the EDT Emulation is configured below to
- ;; ignore attempts to bind functions to the keypad comma key.
- ;;
- ;; Finally, F2 through F12 are also available for making key bindings
- ;; in the EDT Emulation on the PC. F1 is reserved for the GOLD key,
- ;; so don't attempt to bind anything to it. Also, F13, F14, HELP, DO,
- ;; and F17 through F20 do not exist on the PC, so the EDT emulation is
- ;; configured below to ignore attempts to bind functions to those keys.
