j> So how do you do "out of band" operations, like telling a tape j> drive to skip forward to the next mark? You have a control file associated with it. As a hypothetical example, a terminal would have one file for doing character reads and writes, and another for reading and writing control commands like set/get baud rate, and so on. The system works pretty well, though I have a notion that retrofitting something similar onto <insert-Unix-of-your-choice> would be pointless. <b
