edt: Supported terminals
2 Terminals/Keyboards that are Supported
****************************************
Keyboards used under a Window System are supported via the ‘edt-mapper’
function. The first time you invoke the emulation under a window
system, the ‘edt-mapper’ function is run automatically and the user is
prompted to identify which keys the emulation is to use for the standard
keypad and function keys EDT expects (e.g., <PF1>, <PF2>, <KP0>, <KP1>,
<F1>, <F2>, etc.). This configuration is saved to disk read each time
the emulation is invoked.
In character oriented connections not running a window manager,
built-in support for the following terminals/keyboards is provided:
1. DEC VT-100 series and higher. This includes well behaved VT clones
and emulators. If you are using a VT series terminal, be sure that
the ‘TERM’ environment variable is set properly before invoking
emacs.
2. PC AT keyboard under MS-DOS.
Be sure to read 
Platform-specific notes to see if those notes
apply to you.
