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 -- С уважением, Прокопьев Евгений
