While the majority of the iPhone's easter eggs and secrets have over time been discovered, pulled apart and analysed to the umpteenth degree, the smartphone continues to have one, little-known trick up its sleeve: A hidden serial port. The inherent possibilities are endless: Network engineers have talked of even bringing their phone into server rooms, rather than having to use a laptop or remote terminal.
According to Chris Pollock at io Networks: "the real benefit in all of this is that there are so many console packages for iPhone in Cydia now that you can have a fully functional computer, as useful as a linux box, but without carrying around a laptop".
One company has already tried to jump on that boat but even though its purpose-built accessories were announced in February, they are yet to hit store shelves. The solution: Build it yourself.
Pollock compiled a step-by-step guide to do exactly that, thanks to his own handiwork and the diagrams at pinouts.ru. We reproduced it here with his permission.
