Please forgive my earlier muddy question, I'll try to make it clear
this time.

Once upon a time, there was a tedious application like this:

DOS -> multiport serial card -> N x emulated-wyse50-terminals

Now, this application wants to run in two separate locations,
but still with "DOS" appearing only once:

N x wyse50 -> (mux) --phone-or-ether-> (demux) -> DOS <- N x wyse50

These aren't really terminal sessions, except as "DOS" sees them
that way. The traffic does not need to be secure. All we're looking
for is to be able to

1. multiplex the remote serial streams into one stream
2. transport the stream to the "local" location via telephone
   to begin with, then ethernet ultimately when we can
3. demultiplex the serial streams to make it appear as if these
   additional remote serial ports were just other serial ports at the
   local site.

Unix and the multiport serial cards are only serving as data transport
and mux/demux, they don't need to care what the traffic is in any way.

I'm looking for either app code already written to do this, or code
to hack to create this service.

Much obliged ...
