How do you calculate the count of bytes you sent on an AT modem ?

Or in the code... ;-)

It looks in /proc/net/dev (at least if it is like ifconfig that it is
supposed to have replaced). I would be very much surprized if a sane
driver would count anything else than the actual bytes on the wire.
That's the only meaningful statistics from its point of view, isn't
it?
