要求通过程序代码设置好串口号，波特率，发送16进制数据，然后接收16进制数，并16进制显示。

各位大侠，帮帮我吧

serialPort1.PortName = comboBox1.SelectedItem.ToString();
                        serialPort1.BaudRate = Convert.ToInt32(comboBox2.SelectedItem.ToString());
                        switch (comboBox3.SelectedIndex)
                        {
                            case 0:
                                serialPort1.Parity = Parity.None;
                                break;
                            case 1:
                                serialPort1.Parity = Parity.Odd;
                                break;
                            case 2:
                                serialPort1.Parity = Parity.Even;
                                break;
                            case 3:
                                serialPort1.Parity = Parity.Mark;
                                break;
                            case 4:
                                serialPort1.Parity = Parity.Space;
                                break;
                        }

                        serialPort1.DataBits = Convert.ToInt32(comboBox4.SelectedItem.ToString());

                        switch (comboBox5.SelectedIndex)
                        {
                            case 0:
                                serialPort1.StopBits = StopBits.One;
                                break;
                            case 1:
                                serialPort1.StopBits = StopBits.Two;
                                break;
                            case 2:
                                serialPort1.StopBits = StopBits.OnePointFive;
                                break;
                        }
                        serialPort1.Open();
