PC 通过串口工具在发送节点A 端输入想要发送的数据，点击发送，在接收节点B 端 PC 上的串口工具上，可以看到节点B 收到的内容。如要发送10 个字节内容为11 22 33 44 55 66 77 88 99 AA 的数据/时，在发送节点A 端的串口工具上输入 0A 11 22 33 44 55 66 77 88 99AA，其中0A 代表要发送数据的长度，以16 进制表示。在接收节点B 端的串口工具上就可以收到相应的数据。-PC through the serial port tool sending node A wants to send data from client input, click on send, at the receiving node B-side on a PC serial port tools, you can see the node B received. If you want to send 10 bytes of content 11 22 33 44 55 66 77 88 99 AA of the data/pm at the sending node A on the input side of serial port tools 0A 11 22 33 44 55 66 77 88 99AA, in which you want to send on behalf 0A the data length to 16 hexadecimal said. Node B at the receiving end of the tool on the serial port can receive the corresponding data.
