OP6800 / Vinculum VDIP1 comm

Rabbit

I am trying to establish a serial link with a Vinculum VDIP1 chip from a OP6800. This is how I have setup the connections:
For the OP6800 the following I/O lines are used:

  OP6800            VDIP1
----------------------------------------------------
  GND            ---   GND
  RxC   (/CTS)<--   /RTS  (AD2)
  +5V            ---   +5V
  TxB   (---)   -->   Rx    	(AD1)
  RxB   (---)   <--   Tx    	(AD0)
  TxC   (/RTS) -->   /CTS (AD3)
  IN12  (---)   <--   /DATAACK#(AD4)
  OUT06 (---)  -->  /DATAREQ#(AD5)

This is the initial code I have:

void main()
{

brdInit();		//required for OP6800 series boards

// Initialize serial portB, set baud rate to 9600
serBopen(9600);
serBwrFlush();
serBrdFlush();

// Initialize serial portC, set baud rate to 9600
        serCopen(9600);
        serCwrFlush();
        serCrdFlush();

serMode(1);

for(;:wink:
{
}
}

For what I understand the leds on the VDIP1 should flash and then turn solid when I power up. In my case the leds never stop flashing.

Can anyone help?

Thank you,
