I've never done this before, but what is the methodology of sending information through a VB app over an ethernet network? Basically I have a Windows machin (that the VB app will be running on) and a few non-PC machine controllers that have ethernet on them. All the controllers will be receiving are a few bits at a time, so traffic on this network will not be very high. Is there some built in functions that I'm just not seeing? Any help would be greatly appreciated.
