How to Read Device Data From serial port
- by Aamir Khurshid
I have one device which sends data on COM port say on COM13. Now i want to read that data and display it in the RichTextBox or in any text control.
I have written the application with the help of IO and IO.Ports but comport.DataRecived event does not fire, even though device is sending data on that port.
I have some software on which i define the port number and it successfully display data, which insure me that data is receiving on the Port but i am unable to receive.
Is there any way i can read data?
comm.Parity = cboParity.Text;//None
comm.StopBits = cboStop.Text;//One
comm.DataBits = cboData.Text;//8
comm.BaudRate = cboBaud.Text;//9600
comm.DisplayWindow = rtbDisplay;//Null
comm.PortName = "COM13";
comm.OpenPort();
cmdOpen.Enabled = false;
cmdClose.Enabled = true;
cmdSend.Enabled = true;
public bool OpenPort()
{
if (comPort.IsOpen)
{
comPort.Close();
}
comPort.DataReceived += new SerialDataReceivedEventHandler(comPort_DataReceived);
comPort.PortName = _portName;
comPort.Open();return true;
}
