Using Ericsson T60d Cell Phones as Modems?

Garfipus asks: "I have an Ericsson T60d cell phone that I use for cellular modem access. It works fine on a WinME laptop, but I'd like to use it on my PowerBook (and with a miracle, on my Newton 2100). I looked at the .inf file from the Sony Ericsson support website, and added the modem strings to a modem script under Mac OS 9, but it doesn't work. If I dial, the system doesn't see the modem and times out. A terminal emulator works, and allows me to issue commands. I can dial voice calls with ATDT, but that's about it. Any input on correct configuration settings for any non-Windows OS? I'd get a T68i (using that one is easy), but Cingular doesn't appear to support it."
