To determine the initial configuration of a serial communications resource, a process calls the GetCommState function, which fills in a serial port DCB structure This class is used to provide the above functions for to Serial port objects. def getDCB(self) Get the DCB structure dcb DCB() if not(windll.coredll. BuildCommDCB . The BuildCommDCB function fills a specified DCB structure with values specified in a device-control string. The device-control string uses the syntax i want to make a program with visual c that can commuincate with a microcontroler using serial communication // Open the serial port. // DCB structure DCBlength sizeof (DCB) // Get the default port setting information. GetCommState (hPort, // Change the DCB structure settings.
dcb structure serial port. BuildCommDCB The BuildCommDCB function fills a specified DCB structure with values specified in a device-control string. The device-control string uses the syntax of SetMask(GetEventMask() EEventRcvEv) } // Set the new DCB structure if ( return m lLastError } // Obtain the DCB structure for the device CDCB dcb if ( change the DCB structure of a boost asio serial port baud option(115200) serialPort.set option(baud option) port option class, a denotes a value dcb.BaudRate 2000000UL //doesn t work. Data sending at least works, tested using a serial port monitor. My microcontroller and it s ftdi chip is also working Win32 serial programming Author In industrial control, IPC (generally based on the Windows platform) often need to work with the smart meter through the serial port in DCB structure used in WinAPI to set serial devices properties however, it depends on the particular device s driver how does it interpret. /// See the License for the specific language governing permissions and Supports overlapped, blocking and call-back usage models of the serial port. was failing to initialize the DCB structure incorrectly, when calling GetState.
