Hey Tony, For my first AVR project, I would like to build a small digital voice recorder with a tiny radio-remote control. Suggestions on how to get started? Shamoon --- In AVR-Chat@yahoogroups.com, "Tony Vandiver" wrote: > Shamoon, > > Depends on a lot of stuff. Do you have a ha

Hi Greg- This document has some good information about caller ID service: http://www.epanorama.net/documents/telecom/cid_bellcore.html It indicates that the signalling spec for Caller ID is simply Bell 202 signalling. This means that you could go out and find yourself an old mode
