c++builder、delphi是否直接提供了对于串口操作的控件或者函数

Question

你可以使用MsComm控件，是由微软提供的activex控件。可以在ActiveX的控件选项中添加。

Answer 1

我的朋友在c++builder中使用过一个串口读写控件，我想肯定有的。
下面是一段读写的代码：主程序中收发数据
void __fastcall TMainForm::fashu()
{
    //TODO: Add your source code here
        int i;
        Comm1->Write(fahuan,m_nCount);
        while(1){
                i=Comm1->OutQueCount();
                if(i==0)
                        break;
        }
}
void __fastcall TMainForm::jieshu()
{
    //TODO: Add your source code here
    //TODO: Add your source code here
        int nLen,k,i,nTimeOver,nCountTemp,nRetry=0;
        bool bTm,bOver,bGroupOver=false;
        unsigned char buf[1024];
        nCountTemp=m_nCount;
        while(!bOver){
                bTm=false;
                bOver=false;
                m_nCount=0;
                nTimeOver=0;
                bGroupOver=false;
                while(!bGroupOver){
                        nLen=Comm1->InQueCount();
                        if(nLen>0){
                                nTimeOver=0;
                                k=Comm1->Read(buf,512);
                                for(i=0;i<k;i++){
                                        jiehuan[m_nCount]=buf[i];
                                        =f((jiehuan[m_nCount]==0xff)&&(bTm==false)){
                                                bOver=true;
                                                return;
                                        }
                                        =f((bTm==false)&&(jiehuan[m_nCount]==touming)){
                                                bTm=true;
                                                continue;
                                        }
                                        m_nCount++;
                                        bTm=false;
                                }
                        }
                        else{
                                Sleep(1000);
                                nTimeOver++;
                                if(nTimeOver>5){
                                        bGroupOver=true;
                                }
                        }
                }
                nRetry++;
                if(nRetry>=3){
                        bOver=true;
                }
                else{
                        m_nCount=nCountTemp;
                        fashu();
                }
        }
}
