Excellent.  Services should be foreground processes, exactly like
this.  You're running it in a terminal now, because you're still in
the testing stages.

Once you're ready to deploy it, you would want to set it up as an
automatically respawning service, under systemd or one of the other
service managers.  E.g. under systemd, you'd create a file in
/etc/systemd/system/ with a name ending with .service and contents
something like this:

==============================================
[Unit]
Description=Your description
After=network.target

[Service]
ExecStart=/usr/bin/socat ...
KillMode=process
Restart=on-failure

[Install]
WantedBy=multi-user.target
==============================================

Then "systemctl daemon-reload" and "systemctl enable yourservice.service"
and "systemctl start yourservice.service" and you're done.
