To be honest, I never though of emulated serial lines in simh being 
looked at as a terminal server. I don't think it's a correct way of 
looking at it, but I realize it is a reasonable way to think of it.

Yeah. I hardly ever did that myself, but it's a reasonable approach. 
However, in this case you actually had a terminal server in between 
which converted between the telnet datastream and an actual serial port.

I don't think what simh is doing is exactly comparable. But I don't 
really feel a need to argue about it either.
Now I know what you are talking about. Please continue.
