shown below:
-Port

Even/Odd/Mark/Space.
Flow control is determined by product hardware. For some reason, it cannot
communicate. When communication is blocked, open the flow control to ease.
Flow control allows the data receiving device to notify the data sending device
when it is unable to receive the data, so that it can be stopped. It includes
XON/XOFF,DTR/DSR, and RTS/CTS.
Work mode is determined by product hardware. When the product is RS485
serial port, it will display RS-485. When the product is the RS232 interface, it
will display RS-232.
According to the needs, the user can modify the output state of the DTR and
RTS signals at any time
[Force ON]
RTS signal is automatically set to the ON state after every time you open the
serial port, and it is forbidden to change the user to modify. (When the RTS
flow control mode is turned on, it is invalid.)
[Force OFF]
RTS signal is automatically set to the OFF state after every time you open the
serial port, and it is forbidden to change the user to modify. (When the RTS
flow control mode is turned on, it is invalid.)
[Force ON]
DTR signal is automatically set to the ON state after every time you open the
serial port, and it is forbidden to change the user to modify. (When the DTR
flow control mode is turned on, it is invalid.)
[Force OFF]
DTR signal is automatically set to the OFF state after every time you open the
serial port, and it is forbidden to change the user to modify. (When the DTR
flow control mode is turned on, it is invalid.)
Choose this option to apply the setting to all ports.
