struct termios
  {
    tcflag_t c_iflag;           /* input mode flags */
    tcflag_t c_oflag;           /* output mode flags */

    tcflag_t c_lflag;           /* local mode flags */
    cc_t c_line;                        /* line discipline */
    cc_t c_cc[NCCS];            /* control characters */
