Ok, did not know that one.......all ones I have tried gave 33.6 apart from
when noisy line was used....

Gee, you can only think of 11 Juha ? :-) , I could add more like CPU,
board speed, general system load, quality of UARTs etc, I guess Client
hardware & setup would have covered that, we could go on..........

It really is a how long is a piece of string type thing.........the point I
am making I guess is that the original poster with the x2 modem should not
loose too much sleep as there is no way to increase it too say 100kbps,
which I believe is an improvement, 1 or 2 kbps I call for all practical
purposes undetectable to the user.
Gee I am getting even greener knowing even NZ has the xDSL stuff....... BTW
, can you mail me privately telling me the costs, or a pricing page that I
can send to Telstra...
