Been there, done that. Be a lamb and stop with the nonsense. I'm sure you

Yea, I'm going to have to agree with Denis over Roland. In general it's not good to do synchronous operations (expecially I/O) in the main thread, but Qt I/O is mostly* asyc.
*caveat: data reading/writng is async, but things like QDir::mkDir() are sync. So if you're on a slow 5400RPM disk

Why not? It is an asynchronous. You can do I/O in a main thread, but handle
data in a separate thread (e.g. to parse it). Of course, it depends on the
used communication protocol and etc.
A main limitation is that on Windows all

I think the point is that there's little reason to poll the serial port if
