UART Core with CTS/RTS

Ok I find THE solution: RST/CTS flow control works well. This my code:

int main()

{

char* msg = "Detected the character 't'.\n";

FILE* fp;

char prompt = 0;

fp = fopen("/dev/uart", "r+");

unsigned int uart_status;

unsigned int uart_ctrl;

if(fp)

{

while(prompt != 'v')

{

prompt = getc(fp);

if(prompt == 't')

{

fwrite(msg, strlen(msg), 1, fp);

}

}

fprintf(fp, "Closing the UART file.\n");

fclose(fp);

}

return(0);

}

This code works under Hyper Terminal with "hardware" flow control.

I found the error. It iwas an Altera error.

You just have to change :

CTS: PIN L15 (instead of PIN K15)

RTS: PIN K15 (instead of PIN L15)

for the Altera DSP Stratix II Evaluation Board.
