How do I send HEX numbers(Values) through serial port using LPC2129

Hi Friends,
As I had tried with U0THR(Transmit Hold Register) to send the hex value like 0x4B by using LPC2129 but UART architecture is converting hex value to ASCII value and displaying as ASCII 'K' in serial simulator window. Is there a possibility to send hex values through serial port using LPC2129 if so How can I send hex values through serial port using LPC2129.

Thanks & Regards
