But my problem with Fidonet was not a problem with my modem, but a 
problem with my upstream link, my node. The modem worked perfectly, 
although at the time I might have been using an ADSL connection.

Fidonet was a network of Nodes, aka BBSs. We connected to them by 
phoning them directly. The software optimized the phone call to keep 
them short. Some were long distance.

<https://en.wikipedia.org/wiki/FidoNet>

I connected to Fidonet early in the 90's, and to Internet in the late 90's.


In the subject of winmodems, I bought one by mistake. At that time I 
double booted to Linux, and that blasted thing would not work in Linux 
at all. I think I resold it to a friend what was a happy Windows user.
