 -v
 
 	Verbose output mode.  By default the "main" user output from rvinterf
-	(stdout and/or log file) omits certain packet exchanges that cannot be
-	practically logged in any way other than a raw hex dump: TCH DL and UL
-	bits exchanged with FC firmware TCH tap feature, TM/ETM packet
-	exchanges and G23M protocol stack primitive exchanges are currently
-	envisioned as candidates for such elision from default log output.
-	-v option restores the original behaviour of dumping all such packets
-	in raw hex.
+	(stdout and/or log file) omits certain packet exchanges: for TM/ETM
+	packet exchanges only a one-line summary is printed (no full hex dump),
+	whereas for packet exchanges with FC firmware TCH tap feature only a
+	count of sent and received TCH packets is printed in between other
+	(usually trace) packet types.  With a single -v option a full hex dump
+	is added to the log output for TM/ETM packet exchanges; specifying -vv
+	causes all TCH packets to be dumped in raw hex as well.
