直接到连接地址下载代码周末，没事干，写个简单的串口通信工具，也算是本周末曾来过，废话不多，直接到主题串口介绍　　串行接口简称串口，也称串行通信接口或串行通讯接口（通常指COM接口），是采用串行通信方式的扩展接口。
（至于再详细，自己百度）串口应用：　　工业领域使用较多，比如:数据采集，设备控制等等，好多都是用串口通信来实现！你要是细心的话，你会发现，目前家用国网智能电能表就具备RS485通信总线（串行总线的一种）与RS232可以相互转化（当然一般，非专业的谁也不会闲的蛋疼，趴电表上瞎看,最多也就看看走了多少度电）RS232DB9介绍：1.示意图2.针脚介绍：载波检测(DCD)接受数据(RXD)发出数据(TXD)数据终端准备好(DTR)信号地线(SG)数据准备好(DSR)请求发送(RTS)清除发送(CTS)振铃指示(RI)3.实物图：以下是我购买XX公司的一个usb转串口线：这个头就是一个公头，另一端是一个usb口笨小孩串口工具运行图：1.开启程序2.发送一行字符串HelloBenXH，直接将针脚的发送和接收链接起来就可以测试了（针脚2接受数据(RXD)和3发出数据(TXD)）直接链接,C#代码实现：采用SerialPort1.实例化一个SerialPort[csharp]viewplaincopy在CODE上查看代码片派生到我的代码片privateSerialPortComDevice=newSerialPort();2.初始化参数绑定接收数据事件[csharp]viewplaincopy在CODE上查看代码片派生到我的代码片publicvoidinit(){btnSend.Enabled=false;cbbComList.Items.AddRange(SerialPort.GetPortNames());if(cbbComList.Items.Count＞0){cbbComList.SelectedIndex=0;}cbbBaudRate.SelectedIndex=5;cbbDataBits.SelectedIndex=0;cbbParity.SelectedIndex=0;cbbStopBits.SelectedIndex=0;pictureBox1.BackgroundImage=Properties.Resources.red;ComDevice.DataReceived+=newSerialDataReceivedEventHandler(Com_DataReceived);//绑定事件} 本软件ID:9826709
