Right, those are typically T version only commands.  It should be in
the documents as a note.  The earlier list of timing attributes left
out a critical one, being able to set your position to the accuracy of
the receiver.  While it's probably my poor anttenna siting the various
self-surveys (Tbolt, Res-T,  LEA-6T) I've done are all pretty poor.
