Lorenz,
B+ is the best to use followed by QB and then B. You'll need to check
the docs (Update.txt and/or Access!me) to see which protocol that version
supports (Access! v1.42 supports B+).
The B protocols are backwardly compatable in the order I listed them, so
if the term supports B+, you can use any of the above, if it supports QB,
you can use QB or B and if it only supports B, you can only use B.
