Connecting the Altera UART port to a development kits uart port

[Altera_Forum]

Hi I am working on a bluetooth(BT) development kit. The BT kit has a RS232 serial interface. I program the BT IC using hyperterminal [AT commands]. Now I need to connect the altera stratix ep1s10f780c6 kit's UART/RS-232 to the board directly. I wrote a small code to make a bluetooth connection. However nothing seems to be happening. Can someone assist me regarding this problem? Thanks 

 # include <stdio.h> # include <string.h>  int main() {  FILE* fp;  char prompt=0;   fp = fopen("/dev/uart1", "w+");  fprintf(fp,"AT+BTW0021D226A29E\r\n");    while(1){  prompt = getc(fp);  printf("%c", prompt);  }  fclose(fp);  return 0; }

• check the return value of the fopen call, just to be sure that it was opened correctly 
• you will only see the result of the printf after a line feed character. To begin with you should print a full line for each character received, just to check if anything is there 
• did you check the UART speed, number of bits and parity settings in SOPC builder? 
• can you use an oscilloscope to see if anything is happening on the serial link?

I forgot to mention that the code works perfectly fine when connected to PC [using serial port] .. I can see the data being displayed on hyperterminal..and also i can type data from the hyperterminal.. however i cannot see the data when i plug my serial port into the bluetooth dev kit.. the development kit also is programmed using a rs232 port.. so i just replaced the pc with bluetooth dev kit.
