    Thank you for posting here.

    The Serialport class provides Write methods with multiple overloaded forms for writing data, and also provides DataReceive events and various overloaded Read methods are used to read data.

    If you want to write every ten minutes, you can use Timer class.

    A simple example might look like this, but I don’t have a corresponding device, so I didn’t test it, you can use it as a reference.

            private static Timer timer = new Timer();
            private static SerialPort port = new SerialPort("COM1",
            9600, Parity.None, 8, StopBits.One);
            static void Main(string[] args)
            {
                port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);
                port.Open();
    
                timer.Elapsed += OnTimedEvent;
                timer.Interval = TimeSpan.FromMinutes(10).TotalMilliseconds;
                timer.Start();
            }
    
            private static void OnTimedEvent(object sender, ElapsedEventArgs e)
            {
                port.Write("something");
            }
    
            private static void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
            {
                string res = port.ReadExisting();
                //Save to file......
            }

    Hope this could be helpful.

    Best Regards,

    Timon
