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? Thanks All. -- This message was sent on behalf of tony.gugo@gmail.com at openSubscriber.com http://www.opensubscriber.com/message/grub-devel@gnu.org/10640386.html
