I've started trying to get the internal modem to work. I can talk to it via ttyS1 and can do normal modem stuff with it. Haven't managed to use it as a phone yet though. Chris Lawson hinted that the codec is connected to one of the DSP serial ports, but the data sheet for the modem shows the codec connected directly to the modem. Is there a switch somewhere (in on the the latches) to control what the codec is connected to?
