I have wondered why Mathematica does not support my i/o capabilities that can be readily used with a wider range of hardware. My specific application is the kind of things that are typically done with LabView. Mathemaica's built-in Java would seem to be the streamlined way to gain access to these i/o capabilities. You might already have a better MathLink idea in mind if you're big into C, etc., but if not, I think the "way to start" is to use Java and the i/o packages that are available for it. Not 100% sure since I haven't done this---I have only thought about doing it---I'd be interested if others have more efficient suggestions.
