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

45 | The choice is controlled by the variable interrupt_input. | |
46 | Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO) | |
47 | ||
48 | SIGIO can be used only on systems that implement it (4.2 and 4.3). | |
eb8c3be9 | 49 | CBREAK mode has two disadvantages |
20c428fd JB |
50 | 1) At least in 4.2, it is impossible to handle the Meta key properly. |
51 | I hear that in system V this problem does not exist. | |
52 | 2) Control-G causes output to be discarded. | |
53 | I do not know whether this can be fixed in system V. | |
54 | ||
55 | Another method of doing input is planned but not implemented. | |
56 | It would have Emacs fork off a separate process | |
57 | to read the input and send it to the true Emacs process | |
58 | through a pipe. | |
