Multi-tty support depends on two features:

  . the ability to have more than one display_info object, so that
    some could be used for TTY frames and others for GUI frames
  . the ability to open a TTY frame on a named tty device, see

emacsclient and server.el use these two abilities to request creation
of a new frame either on a different TTY device or on a different X
display.  The files where this functionality is implemented are
emacsclient.c, server.el, frame.el and frame.c.
