Hi there, I'm wondering, does the internal modem on the DreamCast understand and listen for AT commands from the Dreamcast, when dialing etc? I'm wondering if in that modem interface, there is a spot where the signal going to and from the modem chip are serial. i wonder if it can be tapped, and then coverted down to 3.3 volt levels to work with little serial based wifi or serial based rj45 based interfaces... some of them will respond to at command sets... just wondering. I'm very new to the dream cast so I have a lot of reading to do. I just thought this might be an alternative to the raspberry pi, (Which I am eager to try)
in the mean time, I'm getting my parts together for the Raspberry Pi option
Cheers.
