The example demonstrates simple data exchange via USART. When PIC MCU
receives data, it immediately sends the same data back. If PIC is connected to the
PC (see the figure below), you can test the example from mikroC terminal for
RS232 communication, menu choice Tools > Terminal.

Usart_Write(char data);

Function transmits a byte (

) via USART.

USART HW module must be initialized and communication established before using
this function. See 

Usart_Init
