-  PURPOSE : handle ACI command request primitive. It is only a
-            signal and must not be freed by PFREE.
+  PURPOSE : handle ACI command request primitive. The original comment
+	    said "It is only a signal and must not be freed by PFREE",
+	    but it appears to have been wrong even before we touched
+	    this code.
+
+  FreeCalypso change: this primitive (not signal!) was originally used
+  for by TI's _SIMULATION_ environment (the code in ati_src_tst.c,
+  removed in the TCS3.2 version we got), but we have repurposed it
+  for our AT-over-RVTMUX implementation in ati_src_rvt.c.
