I have a question not about a PowerPC Mac, but rather about a Motorola Mac. Perhaps this section is the wrong place for this post, and if so, please forgive me. I'm trying to connect my PowerBook 180 to the Internet. It has a built-in modem. I also have a PowerMac G5 with a built-in modem. I thought I would be able to use the built-in-to-OS X Internet Connection Sharing to allow me to connect my PowerBook to the PowerMac via a phone cable and share the PowerMac's Ethernet connection. However, it seems I can only use Internet Connection Sharing to share via Ethernet, Firewire, or Airport. Is there any way I can share over the modem? Thanks!
