void main()
{
int chunk = 0x1E;

TRISC = 0b10101111;
SPBRG = 0b00011001;
TXSTA = 0b00100100;

what is chunk?
and know you do not need to initialize SPBRG just write Usart_init(9600);
it initialize at 9600 baud remember u must have set the same bausd for ur terminal

check from www.mikroe.com the circuits from boards in order to be sure how you should do the connections.

and take the source in microC.

the code works perfect.

may be you should change the ports depends on your hardware.
Also, are you sure about your connections?
