I would say this model is not capable of esp. I'd say the original assessment was correct in that ESP was the *only* possible way to read the status of a UPS which doesn't have an external monitoring interface. :-) The very very old units often had simple status lines which could be monitored with special software thru a parallel printer port. If the UPS has a warning buzzer he could put a microphone on a sound card and listen for the buzzer. The buzzes often come faster just before the UPS breathes its last breath. If one does such a thing we've already got a name for it, ESP. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
