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. */ #define INTERRUPT_INPUT /* * Define HAVE_SOCKETS if the system supports sockets. */ #define HAVE_SOCKETS /* * Define HAVE_UNIX_DOMAIN if the system supports Unix * domain sockets. */ #define HAVE_UNIX_DOMAIN /* * Define HAVE_PTYS if the system supports pty devices. */ #define HAVE_PTYS /* * Define NONSYSTEM_DIR_LIBRARY to make Emacs emulate * The 4.2 opendir, etc., library functions. */ /* #define NONSYSTEM_DIR_LIBRARY */ /* Define this symbol if your system has the functions bcopy, etc. */ #define BSTRING /* subprocesses should be defined if you want to have code for asynchronous subprocesses (as used in M-x compile and M-x shell).
