Interfacing DHT11 with PIC16F877A

Hi eveyone,
I need a help in programming for DHT11 interfacing with PIC16F877A.
I need to transfer my data on Rx, Tx pin of micro controller.
There's a code for on interfacing with LCD but whenever i am modifiying the code for USART my data is not coming on Rx Tx pin.
Please help me with the code.

CODE:

char message1[] = "Temp = 00.0 C";
char message2[] = "RH = 00.0 %";
unsigned short TOUT = 0, CheckSum, i, Check;
unsigned short T_Byte1, T_Byte2, RH_Byte1, RH_Byte2;
unsigned short Data, DataDir, heck ;
char usart_rd;

void StartSignal(){
DataDir = 0;
Data = 0;
Delay_ms(25);
Data = 1;
Delay_us(30);
DataDir = 1;
}
unsigned short CheckResponse(){
TOUT = 0;
TMR2 = 0;
T2CON.TMR2ON = 1;
while(!Data && !TOUT);
if (TOUT) return 0;
else {
TMR2 = 0;
while(Data && !TOUT);
if (TOUT) return 0;
else {
T2CON.TMR2ON = 0;
return 1;
}
}
}
unsigned short ReadByte(){
unsigned short num = 0, t, i;
DataDir = 1;
for(i=0;i<8;i++)
{
while(!Data);
TMR2 = 0;
T2CON.TMR2ON = 1;
while(Data);
T2CON.TMR2ON = 0;
if(TMR2 > 40) num |= 1<<(7-i);
}
return num;
}

void interrupt(){
if(PIR1.TMR2IF){
TOUT = 1;
T2CON.TMR2ON = 0;
PIR1.TMR2IF = 0;
}

{
message1[7] = T_Byte1/10 + 48;
message1[8] = T_Byte1%10 + 48;
message1[10] = T_Byte2/10 + 48;
message2[7] = RH_Byte1/10 + 48;
message2[8] = RH_Byte1%10 + 48;
message2[10] = RH_Byte2/10 + 48;
message1[11] = 223;
Lcd_Cmd(Lcd_CLEAR);
Lcd_Out(1, 1, message1);
