    Instead of return 0, which means EOF. There's no good way to detect EOF on
    continuously active bus like UART, and treat timeout as just temporary
    unvailability of data. .read() method of UART object will return None in
    this case (instead of 0, which again measn EOF). This is fully compliant
    with unix port.
