![]() ![]() ![]() It has standard USB connector on one end, proprietary Sony data connector on the other, plus a little box in the middle. PL2303-based data cable for Sony Ericsson T226 In this article, I will show how to modify data cable originally intended for Sony Ericsson T226 phone into general purpose USB-to-serial. ![]() However, any old cell phone data cable is essentially a USB to serial converter and can be used as such with not much difficulty. The converters are available from many places and cost around 15 dollars.

Using these functions while sharing serial port with peripherals is never trivial and often impossible. At the same time, standard size Arduino comes with just one asynchronous port – and the same port is used to load compiled sketches and print debug messages. Xbees, Bluetooth and WiFi embedded adapters, standalone GPS modules are often equipped with asynchronous serial data port. Despite being quite old, asynchronous serial interface is still popular these days. ![]()
