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.
