说明：  使用方法: 1.在baud rate里设置通讯的波特率 2.在milliseconds to wait的毫秒数要大于等于20,这样可以保证收发数据的成 功率. 3.在顶端的string to write 的文本框里写入要发送的数据,点WRITE发送数据,然后就可以在read string的文本框里看到从底层设备送回来的数据(当然,具体发什么和该收到什么取决于你使用的设备的具体协议) 4.点EXIT退出程序
(Use: 1. In the baud rate to set the communication baud rate. In milliseconds to the wait of the number of milliseconds to greater than or equal to 20, which can guarantee the success rate of the transmitting and receiving data. The top of the string to write text box write the data to be sent point WRITE to send data, then you can read string in the text box to see the data sent back from the underlying equipment (of course, specific hair and the receipt of what depends on the equipment you use specific agreements). point EXIT to exit the program)
