help me to run program for PIC16F886 interface with uart

[micky2406]

here i attached the code. i used MPLAB ICD3 for programming with H-tech compiler. i am not able to receive any data from this code. please help me

#include <pic.h>
#include <stdlib.h>
#include <stdio.h>


unsigned char cUART_char;
unsigned char cUART_data_flg;
void init_uart(void);
void UART_putc(unsigned char c);
void InterruptHandlerLow ();

void main(void){
TRISA = 0;
PORTA = 0;
TRISB = 0;
PORTB = 0;
ANSELH = 0;
ANSEL=0X00;
cUART_char=0X61;
init_uart(); // init UART module

while (1) // infinite loop which handles ncoming data as they arrive
{
UART_putc(cUART_char);
if (cUART_data_flg==1)// if new data available, send it back through USART tx line (echo it)
{
UART_putc(cUART_char);
cUART_data_flg=0; // clear new data flag so one charactor will echoed once
}
}
}
#pragma code
#pragma interrupt InterruptHandlerLow

void InterruptHandlerLow ()
{
if (RCIF==1)
{
if(RCSTA&0x06)
{
CREN=0; //Overrun error (can be cleared by clearing bit CREN)
cUART_char=RCREG; //clear Framing error
CREN=1;
}
else
{
cUART_char = RCREG; // read new data into variable
cUART_data_flg = 1; // new data received. so enable flg
}
}
}

void init_uart(void)
{
TRISC7=1; //Make UART RX pin input
TRISC6=0; //Make UART TX pin output
SYNC = 0; // enables for asynchronous EUART
SPEN = 1; // enables EUSART and sets TX (RC6) as output; ANSEL must be cleared if shared with analog I/O
CREN = 1;
TX9 = 0; // 8bit mode RX9 = 0;
TXEN = 1; // enables Transmitter
BRGH = 1; // baud rate select BRG16 = 0;
SPBRG = 25; //baud rate select 9600@4Mhz SPBRGH = 0;
RCIE=1; // receive interrupt enable
GIE=1; // global interrupt enable
PEIE=1 ; // Peripheral Interrupt Enable bit
}

void UART_putc(unsigned char c)
{
TXEN=0;// disable transmission
TXREG=0x61; // load txreg with data
TXEN=1; // enable transmission
while(TRMT==0) // wait here till transmit complete
{
}
}

You will have to ask on the HiTech forum as this forum are for PICC users.

yeesh...this confirms why I chose CCS C compiler a few years ago(V2.5xx)! Just a couple lines of CCS does ALL that....and WORKS first time!!
