firewire camera control

[Lawless McNutty]

Hi,

I covert the linux command dvcont

http://linuxcommand.org/man_pages/dvcont1.html

And I've been reading the source code (which I won't paste here or else your life will become GPL)

Using libraw1394 they send 44 bytes (if my counting is correct =) of data to the node and the camera starts playing (or one of many exciting functions).

I've been reading through /usr/src/sys/dev/firewire/ but can't spot where a similar transaction could take place and the naming conventions don't seem to overlap.

I'm going to bed now, but while I sleep can anyone out there offer some assistance of where I should be looking ?

is it to do with PHY ?

It is a shame that the firewire driver writer wasn't concerned with cameras !
