I have an Xp o/s built for me buy Scan computers UK using the above modem and have no other complaints other than it takes me 3-4 attempts to connect. It always comes up "dialling " and then either hangs ( and if I cancel just will not let me dial until it gives up) or if it dials first time I get a ppp error message.... ..It eventually get's me on line ( or I would not be here now ). But... It is annoying. ...The company who built my system had it back and thought they fixed it but did't say how ( amateurs with money .I suppose? )... but it is still giving me grief..........and yes I tried loads of different settings but no joy... any ideas ?
