I've made a small modification to the tut2.c demo to have it call
comedi_data_read() three times for each range available on a pci-das6402/16 on
channel 0 and then again on channel 1.  For the test, I've configured for about
0.4V to be applied on differential channel 0, and I've jumpered channel 1 so
that it has 0V on it.  

I'm seeing three problems: 

1) The first reading in each range looks erroneous.  Is this an instance where
comedi_data_read_hint() should be called with a short settling time before
