It depends. Serial send (TX) is since long not interrupt driven. It works even with disabled interrupts. Receiving is usually interrupt driven, but can be configured to a polling code. It has 2 advantages: smaller code and works almost always. The disadvantage is, that characters may be lost if they arrive too fast. The non-avr platforms are all non-interrupt based.
