How to physically wire the JTAG 10 pins to become a RS232 connector?

I understand that the RS232 must be converted to TTL, I have a tiny board that does so, and out put 4 pins, how to connect them to the JTAG 10 pins, and how to find which FPGA pins are connected to the JTAG pins?

I am using Cyclone III Starter Board.

I found this document (link below), does it help my problem?

Thanks in advance for your help.
