In Germany, you could order an x.25 connection between site A and site
B. I don't know whether this is still possible, but a few years ago, it was.
To my understanding, from the user's point of view, this was a reliable
character stream. Is this correct? Or do I miss something?
So, where is the precise difference to what I get, when I use a "Stream
Socket" in Unix?
I'm just trying to figure out the system model used in the congavoid
paper. That's why I'm interested in these things.
