I wondered about that -- but they don't seem to have the 'special
driver' any more -- if you look at http://www.speedtouch.co.uk/330.asp
you can't download the old version any more -- only the 'extended reach'

Also, comparing the two traces in
http://david.woodhou.se/speedtouch-snoops.tar.gz it seems that they do
both send the same initialisation commands -- it's just different

I haven't tried the "High Speed Driver" yet but I thought we'd already
concluded that was just using ISO mode?
