推荐答案

此处 a> [ ^ ].

The System.IO.Ports.SerialPort[^] class provides a DataReceived event. It fires when data is received, as the name implies.

Subscribing a method to this event, you can then process the data byte-by-byte.

For an article on using the SerialPort, start here[^].

对不起，我不明白你说的话.能否请您描述一下?

Sorry,I didnt understand what you said.Could you please describe more?
