Devices that do single character I/O could be attached to non seekable host OS devices (tty, pipes, etc.) and thus shouldn't count on fseek() and ftell(). These DEVICEs on these simulators do single character I/O and easily can update their POS REGisters to reflect how much data has been emitted. Changing such a REGister will have no useful effect when attached to a non seekable file.
