If the application is just local to you or your organisation, then pick something in the dynamic range.

Otherwise, you should look into registering a port for your use as described.

/etc/services (and other files) just tells the inetd which program to run to handle that port when an incoming request is received. But check with your local manual pages for precise details. Editing these files usually requires root privileges.

These should point to your server program.

> with a tcp port us the Well Known Ports.
Most of the well-known ports are already assigned.

Pick one in the user area, then tell the author / user of the PC program to use that port number in the initial request from the client program to the server program.

Yes, now read about your inetd program, and how it needs to associate that port/protocol with your program.

You only need to configure the inetd.conf & services files when you want inetd to fire off your server. If you run it as a daemon, you can avoid modifying them and just have your server bind to your port at start up.
