81 | The choice is controlled by the variable interrupt_input. | |
82 | ||
83 | Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO) | |
84 | ||
85 | Emacs uses the presence or absence of the SIGIO macro to indicate | |
86 | whether or not signal-driven I/O is possible. It uses | |

88 | ||
89 | SIGIO can be used only on systems that implement it (4.2 and 4.3). | |
8e6208c5 | 90 | CBREAK mode has two disadvantages |
f161d0cc RS |
91 | 1) At least in 4.2, it is impossible to handle the Meta key properly. |
92 | I hear that in system V this problem does not exist. | |
93 | 2) Control-G causes output to be discarded. | |
94 | I do not know whether this can be fixed in system V. | |
95 | ||
96 | Another method of doing input is planned but not implemented. | |
97 | It would have Emacs fork off a separate process | |
