+ /* Emacs can read input using SIGIO and buffering characters itself,

+    The choice is controlled by the variable interrupt_input.
+ 
+    Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
+ 
+    Emacs uses the presence or absence of the SIGIO macro to indicate
+    whether or not signal-driven I/O is possible.  It uses
+    INTERRUPT_INPUT to decide whether to use it by default.
+ 
+    SIGIO can be used only on systems that implement it (4.2 and 4.3).
+    CBREAK mode has two disadvantages
+      1) At least in 4.2, it is impossible to handle the Meta key properly.
+         I hear that in system V this problem does not exist.
+      2) Control-G causes output to be discarded.
+         I do not know whether this can be fixed in system V.
+ 
+    Another method of doing input is planned but not implemented.
+    It would have Emacs fork off a separate process
+    to read the input and send it to the true Emacs process
