Recently I purchased the serial enabled lcd kit as my first foray into Arduino. I've been having a lot of fun with it, and it gave me an idea for a project. I have an Olympia caller id Infoglobe, but don't have a land line anymore. I would rather not open up the unit itself, so I was wondering if anyone knows how to take serial data and turn it into a signal the caller id can use (making the caller id think it's receiving a phone call).
I've modified a phone cable so that I can plug in one end into the caller id and the other into the free pins on the serial kit, but I'm having trouble finding info online on how to send the data in a way that can be read by an existing device. I have found lots of projects and sketches for receiving an fsk signal from a phone line, but nothing for sending it.
