Hi,
The E stands for Enhanced Usart, its basically the same but with some extra features like Sleep/ Wake up on receive.
You do not need a Usart module to send out serial data, you can simply use your program to send out the data, known as a software usart or bit banging.
With Hardware Usart the incoming or outgoing byte of data is passed to / from the main program code and the Usart module takes care of all the complicated timings.
You don't say what programming language you are using ; just do a web search for Pic Usart tutorial to see many examples.
