You need to create a link to the printf ( )  function with writing a 
putchar( ) function that links to your Comm write functions so that printf 
( ) can link to the comm port such as:

/************************************************************************************************************************
Name:       putchar
Descr:      This routine is called by printf to output character strings 
to the
                                console. The function sends data out com1.

Inputs:     INT_32  ch = character to send to serial port
Outputs:    INT_32 status -   0 = Character written OK
 1 = Error
Rev:        0
************************************************************************************************************************/
INT_32 putchar ( INT_32 ch )
{
        return(Com1_write(ch));  // Write character to Serial Port
} 


Goog Luck!
