A proxy server is a computer, which may also run other services. It may also be a FTP server, web server, mail server as well as proxy server. When you connect to it to use its service, you should tell it which service you want to use.

FTP service is usually on the default port 21, web service on port 80, mail server on port 110. But the port for proxy service is flexible, so a proxy server must definitely tell the user which port the proxy service is on.

If you connect to the port 21 of the server, you are using its FTP service, port 110 to use its mail service and port PROXY (80, 8080, 3124 etc...) to use its proxy service.

Now you should know the 'port' means 'which service'.

Maybe a new proxy server software's default setting is to serve on port 9090, just like most CoDeen proxies are on port 3127/3128.
