quick perusal via the web says that Labmaster is ActiveX capable,
so driving it from VEE should just be a case of getting the
right docs from Labmaster folks. At that poiunt you'll be
adding it as an Active X automation object in VEE and exercising
it from a formula box.

Start with their support folks and get the needed docs- and hopefully
an example program or two using the ActiveX interface.

Depending upon how their code works you'll be able to control the prober by
controlling Labmaster via Active X- or directly from VEE assuming
you can find the docs for that also.
