Hi,

I would like to access the physical registers on my 1394 interface card, to write to a vendor-dependent register. Is this at all possible with XP's 1394bus.sys?? I suspect it can be done through REQUEST_CONTROL, but I have no documentation on REQUEST_CONTROL / IOCTL_CONTROL, and also, the 1394diag example provides no implementation of that.

The register I want to access is paged register 14 on page 7...

Thanks.
