HI Friends,
i am going to read machine Data using COM Port but failed to read. when i read data from other computer using com port then my program work fine but whenever i read data from machine then its not working. Hyper Terminal shows data perfectly and hyper Terminal setting's are
Port= COM3 , Baud Rate=9600, Parity=None, StopBits=One, DataBits=8. My Program is
SerialPort mySerialPort = new SerialPort();
                mySerialPort.PortName = Console.ReadLine();
                mySerialPort.BaudRate = 9600;
                mySerialPort.Parity = Parity.None;
                mySerialPort.StopBits = StopBits.One;
                mySerialPort.DataBits = 8;
                mySerialPort.ReceivedBytesThreshold = 1;
                mySerialPort.Handshake = Handshake.None;
                mySerialPort.RtsEnable = true;
                mySerialPort.ReadBufferSize = 2048;
                mySerialPort.WriteBufferSize = 2048;
                if (!mySerialPort.IsOpen)
                while (true)
                    string indata = mySerialPort.ReadLine();
                    Console.WriteLine("Data Received:");

Solution 1

mySerialPort.RtsEnable = true;

Which transmision control mode do you setup (None, XOF/XON, RTS+CTS)?
How many wires are in transmission cable?
Maybe you should to disable RTS? I don't know - you have the machine :)
