C515C serial port initialization

Would someone be able to tell me how to initialize the serial port on the C515C so that when I send a printf statement I'll be able to read it on HyperTerminal.

It could be that I have not set up the baud rate, stop bit, and flow control on the HyperTerminal so any comments on this would be appreciated

    **********************************************
    ;* Using 10 Bit Baudrate Generator *
    ;* Oscillator frequency = 10.0 MHz *
    ;* Set Baudrate to 9600 Baud *
    ;*********************************************
    BD BIT 0DFH
    SRELL DATA 0AAh
    SRELH DATA 0BAh
    InitSerial: SETB BD ; Baudrate Generator
    MOV SRELL,#0BFH ; (for 10MHz)
    MOV SRELH,#00000011B
    ORL PCON,#10000000B ; SMOD = 1
    MOV SCON,#01011010B ; Init Serial Interface
