If the connecting station is a '1' (regular FBB or whatever) and the
connected to station is a '2' (B2F) won't both use the lowest common
('1') protocol.  If there is no common type -- then there's no way to
exchange messages.

Does this mean the current JNOS is treating the incoming as B2F even
when it's not and the sending station has said it's a '1' only system.
 Maybe there's no way to differentiate the incoming data and thus the
current JNOS is always picking B2F?

It seems there's something missing in the initial exchange of
capabilities if we need to manually tag the bbs's.
