  67    or using CBREAK mode and making C-g cause SIGINT.
  68    The choice is controlled by the variable interrupt_input.
  69
  70    Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
  71
  72    Emacs uses the presence or absence of the SIGIO macro to indicate
  73    whether or not signal-driven I/O is possible.  It uses
  74    INTERRUPT_INPUT to decide whether to use it by default.
  75
  76    SIGIO can be used only on systems that implement it (4.2 and 4.3).
  77    CBREAK mode has two disadvantages
  78      1) At least in 4.2, it is impossible to handle the Meta key properly.
  79         I hear that in system V this problem does not exist.
  80      2) Control-G causes output to be discarded.
  81         I do not know whether this can be fixed in system V.
  82
  83    Another method of doing input is planned but not implemented.
  84    It would have Emacs fork off a separate process
  85    to read the input and send it to the true Emacs process
