Open-AT is an Event-Driven system, and many newcomers find this concept hard to grasp. I recently found this paper which gives a good description of Event-Driven programming in general (nothing specifically to do with Open-AT): Event-Driven Programming: Introduction, Tutorial, History Stephen Ferg, January 2006. [eventdrivenpgm.sourceforge.net/](http://eventdrivenpgm.sourceforge.net/) The Headerless Handlers and Observer patterns are particularly applicable - and the paper gives a good illustration of the “Subscription” metaphor that is so widely used by Open-AT… Note that the paper does treat everything in Object-Oriented terms. Open-AT isn’t exactly “Object Oriented”, but that doesn’t detract at all from the general principles. Hope some find it useful… --- _[View the full topic](https://forum.sierrawireless.com/t/good-paper-on-event-driven-programming/3848)._
