In this case it is an Rfid reader. We have been using these and other serial devices (gps, rfid, scales, cameras) but with this reader and this API I am getting this result. Part of the problem is I don't know exactly what is going on in the API where I am calling the connect into. It would be nice if it would return a fail on its own.
Is there a way to put some kind of timeout on execution of a command?
