hi,

I want to make usb to 9 pin serial chord converter to use in CPU. How can i do it? Pls give any idea.
 

You need a USB to serial converter chip (FT232R is one of them, you can search for others), TTL/CMOS to RS232 levels converter chip (may be MAX232), power supply, some passive devices.

Block is

USB Connector ----> USB to Serial Converter Chip ------ Voltage Translator (to RS232 Levels) ---- 9 pin DSUB Connector

Buying one is lot more cheaper and easier as you get drivers with it.
