Hi,everybody.

I/O port?

Thanks,

What are you looking for the resource manager part or the IO?

IO can be read with

ThreadCTL( NTO_TCTL_IO, 0 )
x = mmap_device_io( size of io, address );
in8(x); // reading

Check out8() for writing.

As for resource manager you should find what you need in the online doc
