Device having knowledge of its own type


Before uploading firmware to a device, I would like to know what type of device I am connected to. The response should be in a machine readable format i.e. a short code. And SiWi to provide a table of the possible codes. I know the same module is inside most of the Fastrack/FXT etc units, but they should be able to interogate some external registers/pins to determine what the overall unit is.
A defined format of response for the firmware would be good too, but this does seem to have settled down since R7.43



One would have thought that this would be necessary for IDS…?
