�������r���c�������������������sF���e�Zd�ZdZ��fdd�Z��fdd�Zedd���Zejdd���Z���Z	S�)	�RS485a5��    A subclass that replaces the write method with one that toggles RTS
    according to the RS485 settings.

    NOTE: This may work unreliably on some serial ports (control signals not
          synchronized or delayed compared to data). Using delays may be
          unreliable (varying times, larger than expected) as the OS may not
          support very fine grained delays (no smaller than in the order of
          tens of milliseconds).

    NOTE: Some implementations support this natively. Better performance
          can be expected when the native version is used.

    NOTE: The loopback property is ignored by this implementation. The actual
          behavior depends on the used hardware.

    Usage:

        ser = RS485(...)
        ser.rs485_mode = RS485Settings(...)
        ser.write(b'hello')
