The Linux kernel provides the serial_rs485 structure to handle RS485
The Linux kernel provides the struct serial_rs485 to handle RS485

Any driver for devices capable of working both as RS232 and RS485 should
implement the rs485_config callback and provide rs485_supported in the
uart_port structure. The serial core calls rs485_config to do the device
specific part in response to TIOCSRS485 ioctl (see below). The rs485_config
callback receives a pointer to a sanitizated serial_rs485 structure. The
serial_rs485 userspace provides is sanitized before calling rs485_config
using rs485_supported that indicates what RS485 features the driver supports
for the uart_port. TIOCGRS485 ioctl can be used to read back the
serial_rs485 structure matching to the current configuration.
