+
+ Emacs uses the presence or absence of the SIGIO and BROKEN_SIGIO macros

+ 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.
