Hi,
If you are using the free tools provided by Microchip, it will have installed HI TECH C Compiler, if not you can download it from the MCHIP website.
Anyways, once it has been installed you can find UART code here:
C:\PROGRAM FILES\HI-TECH Software\PICC\LITE\X.XX\samples\usart
X.XX on my machine is 9.60
