/Initial COM m_ctrlComm.SetCommPort(1) //选择com1 m_ctrlComm.SetSettings("9600,n,8,1") //通信参数设置 波特率9600，无校验，8个数据位，1个停止位 m_ctrlComm.SetInBufferSize(1024) //指定接收缓冲区大小 m_ctrlComm.SetRThreshold(1) //参数1表示每当串口接收缓冲区中有多于或等于1个字符时将引发一个接收数据的OnComm事件

簡單實現如何透過RS-232 Com port 收送資料 Private Sub btnOpenCOM_Click() //設定Com Port 號碼 MSComm1.CommPort = CInt(txtCOM.Text) //設定鮑率,Dataformat MSComm1.Settings = "9600,n,8,1" //開啟Com Port MSComm1.PortOpen = True End Sub

READ COM PORT AND SAVE ITS INPUT TO TEXT FILE

QT5.1编写，通过串口读写数据，显示通过串口接收到的数据并显示出来。将输入的文字通过串口发送出去。-QT5.1 prepared to read and write data through the serial port to display through the serial port to receive the data and displayed. The input text will be sent through the serial port.
