I had in my memory that it used object 63.  Thanks.  My goal is to reverse engineer this protocol at some point and create a new implementation.  If sources for it turn up (for any OS) that would help a lot.  It can't be very much code.

FAL doesn't explicitly do PMR at all; instead it "just works" provided the intermediate nodes are VMS, because of transparent network access in RMS32.
