Very informative replies. Thanks

We actually have used the USB-USB network bridge (the purple USB 1.1
version from Laplink). While they had
their usefulness for a previous purpose, I am not sure if they will
work for this case, unless we do use a serial to
IP redirector in conjunction with this device. If that is the case the
laplink USB-USB network bridge wouldn't be
needed.

Would it be possible to piggyback two of these USB to RS232 devices
together so that each end would have the
USB connction, then connect the two DB9 connectors together. Would
this present a major conflict or could the
device data be transferred both directions? Just a thought.

That's a case where you might, or might not, need a null-modem adapter,
which simply flips a couple of wires to allow direct connection like this.
The documentation for the app should tell you this. IIRC, the old LapLink
serial cables were essentially null-modem cables.

Despite the cost, I can recommend the serial-to-TCP redirector software.
It can bypass a lot of issues and considerations common to serial devices,
and add significant features, such as longer cable runs, more connecting
systems and net broadcast; similarly, there can be security issues.

Check out the free demo versions; these usually work for two weeks or so,
plenty of time to see if it works for you (and possibly to complete the
task). They install in minutes.

A big factor in what will work best is whether you absolutely have to use a
serial port for the app in question.
