 * 说明：
 *     有时候我们可能仅仅是在嵌入系统里使用一下串口，看是否有数据存在，

            -d      Wait up to DELAY ms for TTY output before sending every
                    next byte to it
            -t      Exit if both stdin and TTY are silent for TIMEOUT ms
            -s      Set serial line to SPEED
            -X      Disable special meaning of NUL and Ctrl-X from stdin
