Parallel port read/write to status/control registers

Sup guys, been a while. This is a long shot but figured I'd ask.

I searched and searched but nothing of any substance.
I am using the inpoutx64.dll with C# and Windows 7 64 bit with a 3rd party parallel port PCIe card.
The language doesnt matter as I just need the specifications on how to.

It has a different memory range so I just point my code to address 53264 / D010 and it all works fine for pins D0-D7. Also wondering what the second memory address range is used for.
Here is the link to the 3rd party card - http://www.sybausa.com/productInfo.php?iid=611

So I need to use the S0-S7 (actually S3-S7 since S0-S2 are virtual) status pins for input/output of various data. Also the Control (C0-C7) pins too.

Thanks
Ps, maybe Im overlooking something as been staring at this too long today lol
