title: Read commands line by line of file and send to the camera - c++ qt
body: <p>I need to read commands from a line-by-line file and send to the camera, (each line is a command),
  In C++ qt, how do I read file line by line to the end of the file, and how after that, send it by USB to the camera?</p>
  <p>I would love help even just on my first question...
  Thank you :)</p>
