I am currently working hard to get a decent documentation for my Roadshow TCP/IP stack hammered out, tutorials and everything included.
Just right now I finished editing the chapter describing how one might use the PPP driver included to connect the Amiga to a dial-up Internet service, using a serial port modem or ADSL adaptor, and with a shudder felt like an old man to even remember how this stuff used to work

Now I am wondering whether fleshing out this particular chapter further will actually be useful. Setting up a working dial-up connection is very error-prone, and as these things go, if the setup doesn't immediately work for you, you are left to your own devices to figure out what went wrong. Given how many different things can go wrong, I could probably churn out oodles of "helpful" notes, but...
Are you still using your Amiga serial port to connect to the Internet? Or am I possibly wasting my time trying to get the Roadshow documentation right?
