Answer 4

我用vs2005的串口控件:
写:
private void button1_Click(object sender, EventArgs e)
        {
            if (!sp.IsOpen)
            {
                if (textBox1.Text != "")
                {
                    this.sp.Open();
                    byte[] buf = Encoding.ASCII.GetBytes(textBox1.Text.ToString());
                    sp.Write(buf,0,buf.Length);
                    textBox1.Text = "";
                    toolStripStatusLabel1.Text = "发送成功！";
                    sp.Close();
                }  
            }
        }读:
        byte[] by = new byte[1024];
        private  delegate void SetTexts();
        public ClientForm()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            if (!sp2.IsOpen)
            {
                sp2.Open();
            }
            
        }        private void sp2_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {            
           
           
            sp2.Read(by, 0, by.Length);           
            this.Invoke(new SetTexts(SetText));
                   
        }
        public void SetText()
        {
            textBox1.Text=null;
            textBox1.Text += Encoding.ASCII.GetString(by);
         }
