Paul,
Thank you for the clarifications. So 256 should always be set no matter
what, right? Then + 2 for bus list, + 4 for Persistence and +8 for alias?
Shouldn't these be described on the flag word page? Well persistence is but
not that 256 should be set and what 2 and 8 are for? Don't get me wrong
here, I don't demand that such information is documented, I'm very much
aware of the fact that this is an open source project and people are
contributing on their spare time. Just trying to figure out if I could have
got this information somewhere from the documentation or if I'm doing the
right thing asking the mailing list.
