Hi Damien,

Thank you for the patch. I have included it in an updated release 2-3 at http://controls.diamond.ac.uk/downloads/support/ethercat/

I paste below the release notes, also included in the tar file. Note that since release 2-0 we are using a patched etherlab library and there are links to the patch.

Regards,

Ronaldo
