The choice is controlled by the variable interrupt_input. Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO) Emacs uses the presence or absence of the SIGIO and BROKEN_SIGIO macros to indicate whether or not signal-driven I/O is possible. It uses INTERRUPT_INPUT to decide whether to use it by default. 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. */ #undef INTERRUPT_INPUT /* * Define HAVE_TERMIOS if the system provides POSIX-style * functions and macros for terminal control. * * Define HAVE_TERMIO if the system provides sysV-style ioctls * for terminal control. * * Do not define both.
