Asynchronous Read/Writing with libraw1394

Question

I'm trying to get two computers to communicate with each other over firewire. Both of the computers are running Ubuntu 9.10 and both have read/write access to the /dev/raw1394 node. I'm using firecontrol to quickly test sending read/write requests. If I can get it to work with firecontrol, I should be able to figure out how to do the same in my code.

On computer A, I do this:

computerA $ ./commander

Since computer A is on node 1, I send to node 0. Then I go to computer B and read from node 0 and get this:

computerB $ ./commander

I'm using the same offset for both of them. What am I doing wrong and how am I supposed to read/write from/to firewire nodes?

I have these same problems when I try and use raw1394 in my own code.
