Hi Christof,

Hmmm. Since I would want to support commands from different threads coming in, I would need to keep this in the commandProcessor itself. Then essentially this collection just becomes an incoming Queue in that object. Maybe like this:

rfid.CommandProcessor.Command.Add("ATTRIBUTE", "ANTS", "2");

The Add method would keep dishing out the commands/ waiting for responses until the collection was empty. If another is added, later it has to start up again. hmmm. Starting to sound like rolling my own queue is what I need to do.

Thanks for your input and help.
