I have a code to send data to serial port. I just want to make sure that it is sending the data properly. I checked the function’s return value and the number of bytes written and it is success. Is there any other way to actually see the data whatever i am writing?
if(WriteFile(m_hSerialComm, pszBuf, dwSize, &dwNumberOfBytesWritten, NULL) != 0)
I tried to use “Advanced Terminal Port software”
but the data is not coming in that window.
There are several ways to test your software. If you have two serial ports then connect them with a cable and listen on the other port with a terminal application such as the one you mentioned. Otherwise, you could loop back on the same port by connecting pins 2 and 3 together. A hardware-free option would be to use virtual serial ports as provided by tools like com0com.
