GCF provides a convenient architecture. Generally, the following steps are used to operate the serial port: 1. Open the serial port: commconnection cc = (commconnection) connector. Open ("COMM: com3: baudrate = ......"); 2. Open the input stream: inputstream is = cc. openinputstream () 3. Open the output stream: outputstream OS = cc. openoutputstream (); 4. Write Data: OS. Write () 5. Read data: Is. Read () How are they implemented? First, let's look
