Hi Dmitri, Regarding open/close and suspend/resume, I have difficulties finding out what the proper behavior is for the various error states that can appear. I also wonder whether open should commute with suspend or not. It would be of great help to get answers to the scenarios below. 1. From the state (!opened,!suspended), calling open followed by suspend, or suspend followed by open, are we in the same state? 2. From the state (!opened,!suspended), calling open fails. What state are we in? 3. From the state (!opened,suspended), calling open gets us to what state? 4. From the state (!opened,suspended), calling open fails. Where are we? 5. From the state (opened,suspended), calling resume fails. What state are we in?
