Hi all
a very helpful and erudite discussion, this-
my $.02:

and thus confirmation--
(from, IMHO, the most eminent and efficient production designer in
the analog field...kudos! John)
--that the current chosen platform is the BAsicAtomPro and, for good
or ill, this gen-I gadget's idiosyncracies must , of necessity, set
the gropund rules for the first CVS...
and that means RS232.
i would also add, based on my experience with the PSIM, that the RS232
interface supported by the BasicAtomPro is VERY robust.
If you prefer USB there are plenty of external ways to skin that cat.
Mind you, this is not an endorsement of RS232 over USB; merely a
compromise made to get a gen-I CVS designed and built.....soon.
This is an experimenters/hobbyists DIY device not an attempt at a
commercial product as John so succinctly explains...

and the folks who do so will benefit greatly from the coalesence of
expertise and inspitration available in the discussions of this project
as ever thanx to all who are contributing to this effort.
