Abstract

A serial port is a serial communication physical interface through which information transfers in or out one bit at a time. Throughout most of the history of personal computers, data transfer through serial ports connected the computer to devices such as terminals and various peripherals. In this project, the Wi-Fi access point needs to be modified by adding external storage, and upgrading firmware in order for the access point to control the serial port. To add the external storage, the access point needs to connect the SD card reader to the circuit board of access point. While, to make the access point working with serial port, some components need to be added to the circuit board with connecting to the pin headers. After modifying the access point, connecting the access point to a PC with 2 Ethernet cable, one is to the internet, while the other one is to the Pc. Next, access the OPENWRT interface, echo to the transit port, the output will be display at hyper terminal. In conclusion, the main part would be the modifying part on the physical of access point, where adding the components connecting the access point circuit board, and, installation, customization of firmware and packages in order to allow itself for controlling serial port, and SD card.
