    Server I/O Mode
        In non-blocking server I/O mode, the application is required to have an
        event loop that calls gl_get_line() whenever the terminal file

-       To determine which type of I/O gl_get_line() is waiting for, the

+       for. To determine which type of I/O gl_get_line() is waiting for, the
        application calls the gl_pending_io() function.  The return value is
        one of the following two enumerated values.
