It looks like a driver problem. I've been looking at the sources, but the EOM logic escapes me. Has anyone else played with/patched this code? I know the logic is complex due to asychronous IO and early returns. But I can't see the forest for the trees. Thanks, Scott Watters scott.watters@vina-tech.com http://www.vina-tech.com
