Re: How to restore the layout?

[Juanma Barranquero]

A few questions for the experts.

Currently I'm restoring frames in the display they were created.

1.- Is there a way to check from Emacs wheter a given DISPLAY is accessible?

2.- It is acceptable on POSIX systems to try to create X frames if
emacs was started with -nw?

3.- On Windows, after "emacs -nw", creating w32 frames is a no-no.
What is the "correct" or "elegant" way to detect that? Is there
something better than

    (and (eq system-type 'windows-nt) (not window-system))

4.- What about the MS-DOS port? Does it support more than one frame?
