I am interested in finding out about the feasibility of running
asynchronous terminals over a local area network. For example, a Vt100
connected through a "terminal server" box to an Ethernet, and thence to a
Unix host. Another example might be a PC running a Vt100 emulation, again
connected to an Ethernet.

My specific interest is in the performance characteristics of this kind
of terminal operation. What kinds of throughput can be sustained when
dumping a file to the screen? Is it feasible to run a program such as
"vi" which does echoing on each character from the remote Unix system?
How big a factor is the network line speed, as opposed to the overhead
time spent in the network protocol software?

Information from real-life experience would be most welcome, as would
pointers to journal articles, etc.

Thanks in advance,
