急：读写串口的问题

[haplessboy]

我是一个新手，想在vc或c中如何对串口操作？最好有源代码，如果觉得分数太少，可以在给！

为什么这么多人要串口？？

HANDLE hCom,hCom2;

DCB dcb,dcb2;

char data[1024],recv_data[1024];
DWORD len,send_len,error_code;
hCom = CreateFile("com2",
GENERIC_READ | GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
0,
//FILE_FLAG_OVERLAPPED,
NULL);


printf("comm2 handl is %d \n",hCom);

pbuf = data;
len = 1;
GetCommState(hCom, &dcb ) ;
dcb.BaudRate =9600;
dcb.ByteSize =8;
dcb.Parity = EVENPARITY
dcb.fBinary = TRUE ;
dcb.fParity = TRUE;
SetCommState(hCom, &dcb ) ; //串口参数配置
strcpy(data,"123456789");
WriteFile(hCom,data,strlen(data),&len,0);
。。。。。。。。。。。。。。。。

ReadFile(hCom,data,1,&len,0);//第三个参数你自己可能任一设置
