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.

I’m a tinkerer and finally reached the point where I fix more things than I break. When I’m not tinkering, I’m probably editing a book for Maker Media.

    Hey, check out BiT Micro Networks. They make a ton of SSDs…they even might have it in that format already, plus these guys make the crazy large flash drives.

    We had a ton of the 1G Transmeta proc-based Compaq tablets back in the day, but they just didn’t have the performance that we needed.

    I’ve got an MM1110 (UK MM10) with the 1.8″ CF adapter installed. I have a Lexar 300x 8GB CompactFlash card in it with Windows XP, dev tools, etc. installed on it. The fast UDMA 5 CF card makes the machine a lot more usable; compiling, loading apps, etc. are a lot faster than before. Not to mention that the machine is silent now with no moving parts whatsoever (Transmeta = no CPU fan). It’s given it a new lease of life for me. I’ve also upgraded the Wifi to an Intel 2915 ABG mini pci for faster networking. If you find one on ebay or whatever give it a go – makes a great portable second for browsing from the sofa or working out of the office/abroad (tiny, light and powerful enough for most out of office uses). Awesome.
