Once rngd is started and starts reading for feeding, does this cause a
capture of the device?
Eg., as described below if I open the tty and send the 'get me some RNs'
command down it, does it respond nicely to me? And without being nasty
to the rngd?
Same question for the verification command.

Nice! What is the command set?

Looking forward to it!
