2 RS485 Serial Communications
21    half-duplex hardware like an RS485 transceiver or any RS232-connected
32    The Linux kernel provides the struct serial_rs485 to handle RS485
33    communications. This data structure is used to set and configure RS485
36    The device tree can also provide RS485 boot time parameters
41    Any driver for devices capable of working both as RS232 and RS485 should
48    what RS485 features the driver supports for the ``struct uart_port``.
58    From user-level, RS485 configuration can be get/set using the previous
59    ioctls. For instance, to set RS485 you can use the following code::
63 	/* Include definition for RS485 ioctls: TIOCGRS485 and TIOCSRS485 */
74 	/* Enable RS485 mode: */
130    Note: not all devices supporting RS485 support multipoint addressing.
