UART RS485 Auto Flow Control
COM2 supports RS485 auto flow control function for all UARTs.
When enabling the RS485 auto control function, the system will automatically drive
RTS# pin to logic high or low for flow control.
To enable the RS485 auto flow control function, the parity and stop-bit settings must
adhere to one of the following three configurations:
(1) 8 data bits + 1 parity bit + 1 stop bit
(2) 8 data bits + 1 parity bit + 2 stop bits
(3) 8 data bits + 2 stop bits
