Thanks,
In France it started with PPPoA, yet quickly it moved to PPPoE (~1999).
People indeed used PCs not minitels to connect to the new thing of the time (Internet). At the time there was a need to update PCs as most individual or family customers had Windows 98.
My experience is that it added instabilities to PC with Win98 where if I remember correctly PPPoE worked out of the box with Win2K and WinXP (it's was a long time ago).
Anyway most home PCs of the time where not to able to deal with the speed of ADSL. I remember that the owner of a restaurant in Rennes wanted us to pay them a new PC!
