Hello Friends I want to Communicate serial port from Client side.
I have a written code in asp.net but that is executing fine from server side. see code.

SerialPort serial = new SerialPort();
    public string recieved_data;
    //public static string strtemp = string.Empty;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
        }
       
    }

    private void Recieve(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
    {
        // Collecting the characters received to our 'buffer' (string).
        try
        {
            if (serial.IsOpen == false)
                serial.Open();
            if (serial.IsOpen == true)
            {
                recieved_data = serial.ReadExisting();
                clsData.strData = recieved_data;
            }
        }
        catch (Exception ex)
        {
            lblMessage.Text = ex.Message.ToString();
        }
    }
    protected void btnStart_Click(object sender, EventArgs e)
    {
        try
        {
            serial.PortName = "COM1"; //Com Port Name
            serial.BaudRate = 9600; //COM Port Sp
            serial.Handshake = System.IO.Ports.Handshake.None;
            serial.Parity = Parity.None;
            serial.DataBits = 8;
            serial.StopBits = StopBits.One;
            serial.ReadTimeout = 200;
            serial.WriteTimeout = 50;
            if (serial.IsOpen == true)
                serial.Close();
            serial.Open();
            //Sets button State and Creates function call on data recieved
            serial.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(Recieve);
        }
        catch (Exception exp)
        {
            lblMessage.Text = exp.Message.ToString();
        }
    }
    protected void btnStop_Click(object sender, EventArgs e)
    {
        serial.Close();
    }   
}
[Serializable]
public  class clsData
{
    public static string strData = "";
    public static string getclsData()
    {
        return strData;
    }
}

I want to execute this code in Client Side without active-x.....
Please any body can solve this problem.
