I don't think linux has the advantage when It comes to complete novices like me. I think Windows, with all its faults, still is easier to set up and run out of the box than Linux. I think it has a way to go before it is serious competition with windows for anyone other than advanced computer users. The learning curve is very steep. Its such a shame because Linux seems so attractive.
There's a large element of luck in it too, if you aren't already familiar with linux. By that I mean that if you aren't planning on buying hardware that is specifically compatible with linux, it's all down to luck as to how well things will work or not :P Your problem in particular is made harder for me (and most others with plenty of experience) to diagnose because, for the most part, we stopped using dialup a long time ago. Linux support for the so-called winmodems is far better than it used to be (they never used to work, and now, in general, they do). I can probably dig up a *real* external serial modem for you to borrow (or buy, if you like). No drivers needed. I see you're from New Plymouth, so suggesting you come to the Saturday workshop probably doesn't help a lot. Just a question though - you're managing to download files (and send email)somehow, what computer and connection are you using for that?
