完善功能

代码展示：

DTR功能

 private void DTR_chb_CheckedChanged(object sender, EventArgs e)
 {
     if (DTR_chb.CheckState == CheckState.Checked)
     {
         serialPort1.DtrEnable = true;
     }
     else
     {
         serialPort1.DtrEnable = false;
     }
 }

RTS功能

 private void RTS_chb_CheckedChanged(object sender, EventArgs e)
 {
     if (RTS_chb.CheckState == CheckState.Checked)
     {
         serialPort1.RtsEnable = true;
     }
     else
     {
         serialPort1.RtsEnable = false;
     }
 }

发送文件

  private void Send_File_btn_Click(object sender, EventArgs e)
  {
      if (strRead == "")
      {
          MessageBox.Show("请先选择文件！");

      }

      try
      {
          byte[] data = Encoding.GetEncoding("gb2312").GetBytes(strRead);
          sendCount += data.Length;
          Send_count_tssl.Text = sendCount.ToString();
          int pagenum = data.Length / 4096;
          int remaind = data.Length % 4096;
          for (int i = 0; i < pagenum; i++)
          {
              serialPort1.Write(data, (i * 4096), 4096);
              Thread.Sleep(10);
          }
          if (remaind > 0)
          {
              serialPort1.Write(data, (pagenum * 4096), remaind);
          }
      }
      catch (Exception ex)
      {
          MessageBox.Show("发送数据失败" + ex.Message.ToString(), "错误");
      }
  }
