Nope. TCP and UDP are seperate and each is "built on top of" (to use
your terminology) IP. A TCP or UDP packet is wrapped in IP, which is
in turn wrapped in whatever low-level network protocol is needed (e.g.
Ethernet). I am not sure what (if anything) serial lines need. Either
way, the "overhead" is not as bad as you say.
