That does make it clearer. Thanks.
The Dreamcast has a built in modem so it can dial-up servers. That worked well in the old days but phone numbers you could call no longer exist, many don't have PSTN landlines. The task is thus faking a 'PSTN dial-up BBS' which the Dreamcast can call which will then pass the data over ethernet and internet to the desired server to provide the same as what it used to have.
I have that exact set-up from when I was using a Bush Internet Set-Top Box which dialled out to connect to my PC which would produce web pages - TV What's On listings - to be displayed on my TV -
I was lucky. Few have a telephone switchboard in their home, let alone more than one, so some sort of PSTN Line Simulator or Line Voltage Injector will have to be purchased or built. That allows a modem to modem connection and then all the PC host has to do is handle what comes from the modem over serial, send back the data expected.
I am using a Windows 95 PC and its Remote Access Server to convert what comes via the modem to TCP/IP, and have a VB6 program to produce the web pages it sends back.
That's what DreamPi appears to be doing, except not being a web server, just bridging between modem and network, using a USB modem to provide dial-in access.
It should be possible to use a serial modem and a USB-to-serial adapter as suggested, which is likely to be easier than finding a USB modem which works, and probably cheaper too. I would expect anything from an original 1B upwards would be suitable for the task.
