Subject: Re: [PATCH] PCI serial card support
Date: Tue, 21 Jul 2009 04:11:03 -0400	[thread overview]
Message-ID: <32398134.11248163863936.JavaMail.root@wombat> (raw)
In-Reply-To: <200811040038.mA40c2ew022770@los-vmm.sc.intel.com>

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?

Thanks All.
