TFDU4100 (PC infrared serial connection)?

i have this infrared transceiver module tfdu411 : data-sheet here
the recommended circuit is here

well, this circuit is for motherboard with built-in IRDA port , and sure mine does not have one

so , can i built this connect this circuit and connect it directly to the serial 9 pins port ?

if not , is there any way to connect this module the the PC and build an infrared transceiver ?


thank in advance
