Emulating a Cyclades/Annex

[Michael ODonnell]

Anybody have a straightforward HOWTO that explains what's
necessary to mke a Linux box act like a cheap serial-port
concentrator, something like an Annex or Cyclades box?

In other words, I want to rig SystemA such that it has a
serial console with that serial port wired over to SystemB
such that I can say something like

   telnet SystemB somePort

...from SystemC and be connected directly to the console
of SystemA
