Create a converter unit that can be attached to modern phones (like Android devices, iPhone or Nokia N900) via audio jack and will enable bidirectional communication.

We want to support multiple communication ways, e.g.:

• RS-232
• FSK

• [TODO] design circuit
• [TODO] create prototype
• [DONE] write “classic” application (Linux/MacOSX/Windows)
• [IN PROGRESS] write Nokia N900 application
• [IN PROGRESS] write Android application
• [TODO] write iPhone application (should run on iPad/iPod too)

jack pinouts: R2+S: pressed: 280 ohm, not pressed: 2.2k ohm
