Any idea? It was a concious decision by the DT people to exclude most of the ATAGs which provide that information. Only memory information and command line ATAGs are merged into DT. Every other tag is ignored (as there's no place for it in DT.) -- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it.
