  * To send a trigger from the command line you can type:
  *
  * adb forward tcp:14035 tcp:14035
- * echo $'\001' | nc -q -1 localhost 14035
  *
- * $'\001' corresponds to the index_position of loaded sound
- * model, you can also send $'\002' etc. $'\000' is the kill
- * signal for the trigger listening thread.
+ * telnet localhost 14035
  *
- * The default event type is a Recognition event, to specify a
- * type of event, you can send another byte. $'\000' corresponds
- * to a recognition event, $'\001' is a sound model event.
- *
- * adb forward tcp:14035 tcp:14035
- * echo $'\001'$'\001' | nc -q -1 localhost 14035
+ * Commands include:
+ * ls : Lists all models that have been loaded.
+ * trig <index> : Sends a recognition event for the model at the given index.
+ * update <index> : Sends a model update event for the model at the given index.
+ * close : Closes the network connection.
  *
  * To enable this file, you can make with command line parameter
