I want to configure the OXPCIe954 to nDTR auto flow contorol (I want the RS-485 ports). I add the following code at driver open com port. WRITE_REGISTER_UCHAR(Port_Addr + 7, 0); WRITE_REGISTER_UCHAR(Port_Addr + 0xA0 + 5, 0x30);
But the ports are not able to send and receive data. (If I use the oxford's device driver and set the port as RS-485, it works.) Is there any register I forget to configure?
