[cctalk] Cell phone as a dial up modem.

Does anyone know if it's possible, or -- better -- have experience using a cell phone as a dial up modem? I'm wondering about doing something as an alternative to a traditional POTS modem connected to a VoIP ATA. I'd think that treating the phone as a traditional modem with venerable Hayes AT commands might be more reliable than trying to do dial up connections across VoIP. It's been *YEARS* since I've tried to connect a modem to a serial port on a PC, universal or otherwise. Does anyone have any experience with or thoughts about doing this? -- Grant. . . . unix || die
