I need to work with datasockets, but I doesn't have open, close and others functions for datasockets. I only have read and write. I suppose I don't have a plug-in or kit and I need to know what its that plug-in.
I am assuming by the question you have LabVIEW 6i. You no longer need an open or a close...this is taken care of for you. Therefore, you don't need a plug-in or a toolkit.
