just hook up a D9 to the used Port pins.  
in de documantation of Dynamic C is written how to use the seriel port.  
The RCM37xx series has 5 serial ports: A, C, D, E & F.  
on whitch pin these are lockeded you can finde in the user manual of the rabbit microcontroller.

there are a few functions in Dynamic C to send some data over the serial port. For these functions see the Dynamic C Function Reference Manual
