Subject: [Comm] Программирование для COM-порта


> Здравствуйте!
>
> Как в программе на С устанавливать параметры COM-порта?
>
> Ecть следующий код для оффтопика, необходимо написать его аналог:
>
> #ifdef __WIN32__
>    handle = CreateFile(port.c_str(), GENERIC_READ|GENERIC_WRITE, 0,
> NULL, OPEN_EXISTING, 0, NULL);
>
>    if (handle == INVALID_HANDLE_VALUE)
>      throw runtime_error("serial device "+port+" open error");
>
>    DCB dcb;
>    ZeroMemory(&dcb, sizeof(DCB));
>    if (!GetCommState(handle, &dcb))
> throw runtime_error("serial device "+port+" get state error");
>
>    dcb.DCBlength=sizeof(DCB);
>    BuildCommDCB(params.c_str(), &dcb);
>
>    dcb.BaudRate = 600;
>    dcb.ByteSize = 8;
>    dcb.Parity   = NOPARITY;
>    dcb.StopBits = TWOSTOPBITS;
>
>    if (!SetCommState(handle, &dcb))
>      throw runtime_error("serial device "+port+" set state error");
>
>    COMMTIMEOUTS  ct;
>    ZeroMemory(&ct, sizeof(COMMTIMEOUTS));
>    ct.ReadIntervalTimeout = MAXDWORD;
>    ct.ReadTotalTimeoutMultiplier = ct.ReadTotalTimeoutConstant = 0;
>    ct.WriteTotalTimeoutMultiplier = ct.WriteTotalTimeoutConstant = 0;
>    SetCommTimeouts(handle, &ct);
> #endif
