Desoutter controllers reject any stationID/spindleID other than blanks. The serializer could already blank them out, but only via a constructor option decided before we know what we're talking to. Make the mode settable at runtime through the whole stack (SessionControlClient -> LinkLayer -> OpenProtocolSerializer), and turn it on automatically when the MID 2 reply of the handshake reports a supplier code starting with "DE". Detection only ever enables the mode, and is skipped entirely when the caller passed an explicit value, so other controllers keep their current behavior. Note that MID 2 revision 1 carries no supplier code, so detection needs revision 2 or higher. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
