Would the controller be a 154[02]A? People have seen this before. I can't recall, but I seem to think that 8 bytes is about the reconnect length for the controller. Are they located on 8-byte boundaries? Try tweaking your controller parameters. I don't know if this would help, but it could help us work out what's wrong here. Greg
