- Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
-
- SIGIO can be used only on systems that implement it (4.2 and 4.3).
- CBREAK mode has two disadvatages
- 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.
-
- Another method of doing input is planned but not implemented.
- It would have Emacs fork off a separate process
- to read the input and send it to the true Emacs process
- through a pipe.
