51 | Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO) |
52 | ||
bb7b4368 PE |
53 | Emacs uses the presence or absence of the SIGIO and BROKEN_SIGIO macros |
54 | to indicate whether or not signal-driven I/O is possible. It uses | |
32de6484 JB |
55 | INTERRUPT_INPUT to decide whether to use it by default. |
56 | ||
20c428fd | 57 | SIGIO can be used only on systems that implement it (4.2 and 4.3). |
eb8c3be9 | 58 | CBREAK mode has two disadvantages |
20c428fd JB |
59 | 1) At least in 4.2, it is impossible to handle the Meta key properly. |
60 | I hear that in system V this problem does not exist. | |
61 | 2) Control-G causes output to be discarded. | |
62 | I do not know whether this can be fixed in system V. | |
63 | ||
64 | Another method of doing input is planned but not implemented. | |
65 | It would have Emacs fork off a separate process | |
66 | to read the input and send it to the true Emacs process | |
32de6484 | 67 | through a pipe. */ |
