PIC18F4620 USART reception problem

[apexcode]

hello all,
i'm able to transmit from PIC TO PC and view text on hyperterm but what i type in Hyperterm is not received at PIC

please help...

what i'm trying to do is ... what i type at hyperterm is sent back to PC from PIC when received at PIC.........

below is the code ive tried.... and ive attached a screen shot too... which shows the o/p as soon as i s/w on PIC...... after that whatver i type in hyperterm nothing happens...

code:

void main (void)
{

//char rx[8]="Null\n\r";
char rx1='k';
int key;
//init();
TRISB = 0;
PORTB = 0;
TRISD = 0;
PORTD = 0;



OpenUSART( USART_TX_INT_OFF &
USART_RX_INT_OFF &
USART_ASYNCH_MODE &
USART_EIGHT_BIT &
USART_CONT_RX &
USART_BRGH_HIGH,25 );

//initLCD();


while (1)
{

if (DataRdyUSART())
{
if(RCSTAbits.OERR)
{
RCSTAbits.CREN=0;
Nop();
RCSTAbits.CREN=1;
printf("\n\r OERR");

}

if(RCSTAbits.FERR)
{
printf("\n\r FERR");
while(!DataRdyUSART())
{
printf("\n\r FERRin");
rx1=RCREG;
}
}

rx1=RCREG;
printf("\n\rkey detected:");
while(!BusyUSART());
WriteUSART(rx1);

} //end if
}//end while
}//end main

Just a guess, do you need to set the rx pin as an input with the appropriate TRIS?

Alan is correct. Setting TRISC of '0' turns everything to outputs. Also, keep in mind that Hyperterm might need RTS/CTS/DTR/DCD disabled if you don't control these lines.
