_tprintf (TEXT('Serial port %s successfully reconfigured.This Visual C++ code fragment show you how to retrieve data from serial port RS232 using standard serial toolbox available on Visual Studio. Printf ('SetCommState failed with error %d. ', GetLastError()) 57,600 bps, 8 data bits, no parity, and 1 stop bit.ĭcb.ByteSize = 8 // data size, xmit and rcv

Fill in some DCB values and set the com state: Printf ('GetCommState failed with error %d. ', GetLastError()) Build on the current configuration by first retrieving all current Printf ('CreateFile failed with error %d. ', GetLastError()) NULL ) // hTemplate must be NULL for comm devices Open a handle to the specified com port.Ġ, // must be opened with exclusive-access TCHAR *pcCommPort = TEXT('COM1') // Most systems have a COM1 port The following code example demonstrates the use of the SerialPort class to allow two users to chat from two separate computers connected by a null modem cable. _tprintf( TEXT(' BaudRate = %d, ByteSize = %d, Parity = %d, StopBits = %d '),

Print some of the DCB structure values On running my code, receive is getting failed. WriteFile(hCom, buffer, strlen(buffer), &numWritten, NULL) Īnd here is my receiving code:- DWORD numRead īOOL ret = ReadFile(hCom, buffer, 5, &numRead, NULL) Here is my code for sending string:- char *buffer ='hello' Now, I try to send a string and read it back by shorting Rx and Tx pins of my hardware. For this I try this example, which is working fine. I am writing a serial communication code in c++ on Visual Studio 2010.
