    258235Note that if a driver supports TIOCSRS485 (in other words it handles the assertion/de-assertion of TXEN in the driver) this is preferred over using tcdrain() to determine when the FIFO is empty as tcdrain() can have considerable latency at small transmit sizes.

    295 === Cambria ===
    296 The Cambria GW2350 and GW2358 optionally supports half-duplex, multi-drop RS485:
    297  * TL16C752B UART
    298  * MAX3485 transceiver
    299  * TXEN connected to DTR
    300  * '''optional on-board termination resistor'''
    301  * '''optional on-board fail-safe bias resistors'''
    302 
    303 By 'optional' this means the baseboard design supports this, but it is not loaded on standard product therefore would be a Gateworks Special. Contact sales@gateworks.com if interested to see if a configuration already exists.
    304 
    305 Your software must assert/de-assert DTR manually (see [#rs485-example] example code) or the uart driver would need to be modified to add TIOCSRS485 ioctl support.
    306 
    307 
    308 [=#rincon-rs485]
    309 === Rincon ===
    310 The Rincon GW2361 supports half-duplex, multi-drop RS485:
    311  * DM6446 (CPU) UART2 (/dev/ttyS2)
    312  * MAX3485 transceiver
    313  * TXEN connected to RTS
    314 
    315 Your software must assert/de-assert RTS manually (see [#rs485-example] example code) or the uart driver would need to be modified to add TIOCSRS485 ioctl support.
