Hello,

Let me explain the procedure so you can understand fully.I have system which includes microcontroller LPC 2132 and the system has 6 keypad Menu, so, I need to get these menu function to PC. Every key has specific command with which the microcontroller will respond some command. I connected the system(DB-9) and serial interface PC(RJ45) and uploaded firmware through flash magic software. After uploading this, I need to write a programm having some commands according to key button on the keypad of the system. I have created GUI with all essential requirement like baud rate, parity, stop, hex command, connect and send data.

Note<:- When I connect the system and PC through user interface, automatically it show command continuously in terminal which i created on GUI that command which are following

Read = 0x90 & Read = 0x9F

Then I send some hex command in send command then it does not show anything, so, i need to press 'Standbykey' button on the system then I get same command in terminal which is following:-
//Convert a string of hex digits (example: E1 FF 1B) to a byte array. 
        //The string containing the hex digits (with or without spaces)
        //Returns an array of bytes. 
        private byte[] HexStringToByteArray(string s)
        {
            s = s.Replace(" ", "");
            byte[] buffer = new byte[s.Length / 2];
            for (int i = 0; i < s.Length; i += 2)
                buffer[i / 2] = (byte)Convert.ToByte(s.Substring(i, 2), 16);
            return buffer;
        }

        private void btnSend_Click(object sender, EventArgs e)
        {
            sendData();
        }

But, if I change the structure with some command  in btnSend_Click(object sender, EventArgs e) then

        private void btnSend_Click(object sender, EventArgs e)
        {
            case "25520201DE":
            rtxtDataArea.Text = "25520C01UHD-4K02.10.09C2"
            break;
            default:
            rtxtDataArea.Text = "busy"
         }

I get waht I want in terminal(richtextbox). This is the result.

Please let me know any other programm i need to write or change anything. Thank you for your support.Hope you understood my point.
