C# 虚拟串口通信

 

将主端口com8拆分成 com1和com2两个虚拟端口

 com8接收的消息会传递给com1和com2

 

serialport spsend;//spsend,spreceive用虚拟串口连接，它们之间可以相互传输数据。spsend发送数据

serialport spreceive; //spreceive接受数据

private delegate void mydelegate(string indata);

private mydelegate showdelegate = null;

 showdelegate = new mydelegate(show);

 spreceive = new serialport("com1", 19200, parity.none, 8, stopbits.one);

spreceive.datareceived += new serialdatareceivedeventhandler(datareceivedhandler);
spreceive.open();

  void show(string indata)

{

//com1接收的消息

}

private void datareceivedhandler(object sender, serialdatareceivedeventargs e)

{

 serialport sp = (serialport)sender;

this.invoke(showdelegate, new object[] { sp.readexisting() });

}
