Collin Meyer put together a working tutorial for making use of the iPhone and iPod Touch’s RX and TX lines as a standard unix serial port.

This tutorial will explain how to use the serial RX and TX lines on the Iphone as a standard UART serial port. Software on the Iphone can access the UART using the same libraries and functions as in any UNIX software.

With this, you could attach an external GPS unit to your iPhone, or even connect an Arduino and use your iPhone as a data uplink and control system for your next embedded project.
