Trying to fax a multi-page document using "Preview", Print, Send PDF Fax. in OS 10.5.8 but don't know how to change or adjust proper network settings for my G4 to recognize that I want to use the internal modem. My network settings are set for DSL Ethernet right now. I need to change the settings so I can fax a document. I have connected a standard phone line to the computer, what needs to be done to activate this phone line to send a fax?
