Can you help us identify these?

Yes, and when we found out that UI-view, which cannot be u pgraded would not accept them over 2 years ore more ago, we dropped that proposal.  For a few years now he operator-present indicator is now an overlay "O".

Your missintepreted the thread.  My sentence above was saying that ALL software WOULD have to change if we used the ALTNET indicator.  This was as opposed to using the propsed overly-case bit which does NOT effect ALL software...

Big difference.  If you can help identify what software fimware will not pass lower case overlays, let us know...
