The real problem is that some devices don't trigger events properly. I know what to do, just haven't done it yet. The "pulse" function is one of them. "method=euler" disables the truncation error part of step control. In this case, tightening tolerance will get you by. _______________________________________________ Help-gnucap mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gnucap
