[Simh] EXT : LK461 keyboard

[Peter Allan]

Dave,

Thanks for the suggestion, but the link tells me how to remap the keyboard
so it works with xterm (and other) terminal emulators running on Linux.
That is useful background information, but not what I am trying to do. I am
connecting from Linux to VMS using xdmcp, not a terminal emulator, so I
need a method that changes the key mappings for the whole X session, not
just for one application.

Cheers

Peter
