49/* Emacs can read input using SIGIO and buffering characters itself,
50 or using CBREAK mode and making C-g cause SIGINT.
51 The choice is controlled by the variable interrupt_input.
52 Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
53
54 SIGIO can be used only on systems that implement it (4.2 and 4.3).
eb8c3be9 55 CBREAK mode has two disadvantages:
9b71f02b
JB
56 1) At least in 4.2, it is impossible to handle the Meta key properly.
57 I hear that in system V this problem does not exist.
58 2) Control-G causes output to be discarded.
59 I do not know whether this can be fixed in system V.
60
61 Another method of doing input is planned but not implemented.
62 It would have Emacs fork off a separate process
63 to read the input and send it to the true Emacs process
64 through a pipe.
