Re: serial to usb

A simple USB to UART converter (like FT232, CP2102, CP2103) will help you do that. It is basically as easy as soldering the chip, hooking up the wires, and installing the apropiate drivers.. no hokus pokus. If you don't want to do SMD soldering, FTDI, dlpdesign, and sparkfun has breakout boards (DIP modules and alike) for the mentioned chips.

See the attached image in this thread, using FT232. I draw it quite quickly, so you should double-check the connections with the datasheet before using it.

thanks for your help. I want to ask that either I would install a driver for it?

Re: serial to usb

Not sure what you mean... if you are asking whether you'll need drivers, the answer is yes. FTDI provides drivers for their chips (such as FT232) at https://www.ftdichip.com/FTDrivers.htm. If you will be using Silicon Laboratories' chips instead (CP210x), I know SparkFun has made some drivers, available for download at https://www.sparkfun.com/datasheets/SFE_USB_Drivers-v011.zip.

Best regards
