    M2 axial MiG B had decided it wanted to be in program mode, and
can't be read by the MiG box in that state.  Since the MiG box reads
the MiGs serially, all MiGs after M2 axial B in the sequence weren't
read either.  Axial B was put back into the normal mode and the MiG
box rebooted.  All MiGs are reading now.  The nominal value for B is
almost certainly different from before.
