实现serialport测试，包括串口的打开、关闭及所有常用属性的设置

串口链接，通过VS测试 public partial class Form1 : Form { public Form1() { InitializeComponent(); SerialNameSelect(); SelectPortStopBits(); SelectHandShake(); SelectParity(); SerialNumber.SelectedIndex = 0; serialBit.SelectedIndex = 2; SerialDataBits.SelectedIndex = 3; SerialStopBits.SelectedIndex = 1; SerialHandShoke.SelectedIndex = 1; SerialParity.SelectedIndex = 0; } private void SerialNameSelect() { string[] ports = SerialPort.GetPortNames(); foreach (string port in ports) { SerialNumber.Items.Add(port); } } private void SelectPortStopBits() { foreach (string s in Enum.GetNames(typeof(StopBits))) { SerialStopBits.Items.Add(s); } } private void SelectHandShake() { foreach (string s in Enum.GetNames(typeof(Handshake))) { SerialHandShoke.Items.Add(s); } } private void SelectParity() { foreach (string s in Enum.GetNames(typeof(Parity))) { SerialParity.Items.Add(s); } }。。。。。。。。。。
