 In my ''bpq32.cfg'' file, I added the port number to the telnet port, where the fourth entry, ''10001'' is the port for my new application:

-CMDPORT=8005 63001 4565 10001

 ===== Configuring this as a service =====
 Next we'll configure a ''systemd'' service to make sure this script is always running and ready to accept connections.

+Activate it by running:

+sudo systemctl enable rick.service
+sudo systemctl start rick.service
+</code>
+Then check the status to confirm it is working:
+<code>
+systemctl status rick.service
+</code>
+If you need to edit the service file, reload it with:
+<code>
+systemctl daemon-reload
+</code>
+Finally, to see who has used it:
+<code>
+journalctl -u rick.service -f
