Auto detect com port on startup

[Bewgg3]

Currently the com port is hard coded. Start up would be easier if the com port was Auto detected.

Since we should only have one COM port on the computer at a time, would it be possible to enumerate all active COM and just choose the one/ have the user choose? Something like this, haven't read it too thoroughly though:

It seems possible in C#. Can we do something simular in C++?

Also, would it work to ping all com ports and then just select the port that sends back a message?
