Thanks for the reply, but this is not answering my question. I wasn't 
asking how to *configure* the beast (I've already done this 
successfully), I was asking how to verify that it actually works as 

What measurements do I have to take that will show the difference 
between a setup that's actually using the PPS signal from the GPS 
receiver and one that's not (because, for example, the DCD line on the 
motherboard is cracked, to give a stupid example).
