2 RS485 Serial Communications21 half-duplex hardware like an RS485 transceiver or any RS232-connected33 RS485 communications. This data structure is used to set and configure RS48536 The device tree can also provide RS485 boot time parameters (see [2]40 Any driver for devices capable of working both as RS232 and RS485 should49 From user-level, RS485 configuration can be get/set using the previous50 ioctls. For instance, to set RS485 you can use the following code::54 /* Include definition for RS485 ioctls: TIOCGRS485 and TIOCSRS485 */65 /* Enable RS485 mode: */
50 #define RS485 0xF0 macro241 sio_write_reg(pdata, RS485, config); in fintek_8250_rs485_config()334 reg = RS485; in fintek_8250_set_termios()
