推荐答案

您是否正在使用SerialPort类进行连接.该错误可能是由于无效的端口名引起的.下面的代码在这里可以正常工作.尝试此操作，
要创建连接，

SerialPort port = new SerialPort("COM1");

要打开端口

Are you using the SerialPort class for the connection.The error may be due to the invalid port name.The following code works fine here.Try this,
To Create the connection,

SerialPort port = new SerialPort("COM1");

To Opens the port

if (false == port.IsOpen)<br />
      {<br />
        port.Open();<br />
      }

写入数据
port.Write("test");

问候，

To Write the data
port.Write("test");
