Serial Communikation

Hallo,
I have a problem with my XC866. My communication with the hyper terminal doesn´t work. The signs, which I send via the serial interface, are not received in the correct way.
If I use a other program like the normal Terminal the communication works.
If I use my LabView program the communication doesn´t work. I tested the program with a other µC (XC164CM) and LabView receive these data. So the program works in the correct way.
What can I do?

Hi Stefan,

Here is the Keil example for the XC866 which works fine on HyperTerminal (57600, 8-N-1 no flow control).

void main (void) {

 /* Pin TXD_0 (P1.1) is selected for transmission
   * Pin RXD_0 (P1.0) is selected for reception
   * Receiver enabled
   * Mode 1: 8-bit data, 1 start bit, 1 stop bit, variable baud rate
   */
  SFR_PAGE(_pp2, noSST);
  P1_ALTSEL0 &= ~0x02;
  P1_ALTSEL1 |=  0x02;

  SFR_PAGE(_pp0, noSST);
  P1_DIR     |=  0x02;

  MODPISEL  &= ~0x01;
  BCON       =  0x00;
  SCON       =  0x50;

  BG = 0x1C;
  BCON |= 0x01;
  RI = 1;
  TI = 1;

  while (1) {
    printf ("Hello World\n");   /* Print "Hello World" */
  }
}

Regards,
-Chris
