Hi All :)
I'm writing an application in C++/CLI and I have a problem with serial transmission. At the beggining, I got some additional data, which are not supposed to be there. I'm using SerialPort class. Probably buffer should be cleared before the transimission starts. Does DiscardOutBuffer() work similar to fflush() in C? Can you please give me any advice?

Remove "managed C++" from the title, say "C++/CLI". This is the language superseded by C++/CLI, which is a very different thing.

Thanks, you are right, I've changed the title.

I still did not solve this problem. All of your propositions require some external libraries or are dedicated for different class that the one that I'm using :(
