Abstract: DUPLEX provides the capability of having two computers
talk to one another over serial lines while giving the
user access to file facilities. In use, it makes a
PDP-11 runnning RSX-11M appear to be a smart terminal.
However, the combination of being able to talk to two or
more computers from one terminal, and of being able to
transfer files to and from each computer in a clean and
simple fashion, turns out to be extremely powerful and
convenient. It is the poor man's DECnet, giving access
to peripherals on both machines for anything that can be
transmitted over a serial line.
