The choice is controlled by the variable interrupt_input.

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 disadvantages
|
||
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.
