Is it not possible to use 'addlistener' in legacy based programming style? lh = addlistener(Hsource,'EventName',callback) What is 'HSource'? I want to excecute a callback function every 1sec when the data available in the input card exceeds say'5000' points.

What is "legacy based programming style"? What exactly does "data available" mean? When you are talking of a serial connection, a simple callback might be easier.

I am talking about the session based & legacy based interface in data acquisition.I want a function to be called every second when the input data collected by the data acquisition card exceeds some fixed pointsin legacy interface programming.'addlistener' calls a function when 'data available' event occurs. But i dont know its exact usage like what Hsource' means.
