Description: Description This is part 3 of the series to improve and extend the availability of the _read() method. Part 1: #709 Part 2: #711 Part 3: Add the _read() method to the File() connector: This fixes #622 by adding an initial implementation of the _read() method to the File() connector that, until now, was lacking this feature and was raising a NotImplementedError exception. The only way I found for this to work is by the use of the low level os module thanks to its ability to manage file descriptors. No other file access/read method has been successful, at least for me. This implementation does not include any timeout/cancellation ability in case of the file not being accessible, although this is not currently planned for the near future. Features: Implement the _read() method on the File() class. Adapt the File() class. Adapt existing File() printer tests. Add a test for _read() Part 4: #714 Tested with TM-U210 Parallel port printer Regular files
