Personally, I would call the "reset" counter a snapshot S and the real
counter just C and rephrase things a bit, but that is probably a matter
of style.

Your answer wonderfully summarizes the point I was trying to make. ;-)
All I suggest is to replace "do not need additional software" with
"do not need software that is not easily available". (And yes, I
recently had to install additional software on a laptop in order
to use an RS 232 interface while I had Ethernet and ssh readily
available. And with the success of USB, I envision that we will
see more of this happening.)
