„ SP 2 AutoFlow Control [Disabled]
Auto flow control is used in RS-485, is used to tri-state the transmitter when no

When auto flow control is enable, the device monitors the local output buffer for
not empty and empty conditions. If enable, the flow control will force signal to
the desired polarity under the empty or not empty condition.
