This way, when Modbus RTU Master application sends a request to virtual Com-Port 2
(provided by ProCOM), the driver will forward the request to the enabled ProCom-Port 2 of the
Gateway. Then the Gateway forwards the request to the target Modbus device using the pre-set
Modbus device mode and Slave ID.
