stdin/stdout is buffered by default.

Buffering can be turned off as follows:

    setvbuf( stdin, NULL, _IONBF, 0 );

    setvbuf( stdout, NULL, _IONBF, 0 );

    setvbuf( stderr, NULL, _IONBF, 0 );

Alternatively, you can flush stdout as required using:

    fflush(stdout);

Example usage is shown in console.c in the iperf app.
