iMac Fax Modem - AT Commands

I have an iMac G5, and I’m trying to configure it to receive faxes only when it hears a “distinctive ring”. Some people have gotten this to work, while others haven’t.

I can’t get it to work. So, I have two questions:

  1. Do you have any idea how to make this work?

  2. Do you know where I can get a complete list of AT commands that work for my modem? According to System Profiler, I have a “Jump” model modem, that is using the driver “MotorolaSM56K.kext (v1.3.1)”. I’m hoping the AT command list will specifically document a “distinctive ring enable” setting that will work on my modem.

Your modem should support the commands listed on this page.
