something like 'netcat' from the receiving end back into the
serial-ethernet device will work, depending on what you want to do, like
capture the output of some monitoring devices.
(it's a terminal server by another name)

failing that, you'd expect the device to be programmable to telnet into

The manufacturer has to document what TCP ports are used and how.
Terminal server manufacturers often provide some sort of server software
to manage them and/or connect.

There's gotta be a good reason you couldn't use a USB-serial adaptor,
you're no fool and you're work needs good/leading-edge engineering
solutions :-)
