jmri.jmrix.sprog.update.SprogVersionQuery

All Implemented Interfaces:

EventListener, SprogListener

public class SprogVersionQuery
extends Object
implements SprogListener

Get the firmware version of the attached SPROG.

Updated April 2016 by Andrew Crosland: look for the correct replies, which may not be the very next message after a query is sent, due to slot manager traffic. Add Pi-SPROG version decoding.
