(I can't seem to reply directly to David, so...) Hi, Re: > LLIO Error - subsys: 114, proc num:28, error_num: -1 This looks like a "general ports error" from the "IO_DISABLE_TRAPS" routine in Low Level I/O. What does that mean? I have no idea! This probably doesn't help much, but maybe it will spark someone's memory. -- Stan Sieler [log in to unmask] http://www.allegro.com/sieler.html
