The jsm driver still doesn't support the Classic cards, just the Neo 
cards so dgnc would still be needed to support those cards.

I think the right thing would be to put the Classic support into jsm. 
I've started looking at that.  Dgnc and jsm are obviously from the same 
base, so dgnc can be used as guide on what to do.  However, I don't have 
a Classic card so I wouldn't be able to test any of the Classic support.
