The FTP type port is a port that opens a socket for a specific type TCP/IP connection. You can find a listing of services/ports in /etc/services on a Unix machine. Ported software refers to making software run on a platform that it was not originally designed to run on. There are lots of books on TCP/IP that will give you information about the first type of port. I do not know of any book to help you with porting software. Hope this helps....
