I'm a late arrival in the OS X world, and upon launching OS X (10.1) immediately discovered my external US Robotics Sportster dial-up modem (which works fine in OS 9.2.2) is not recognized by my g4-733 when it's running OS X. I've been told that I need a new driver for the modem. Can't seem to find a new OS X compatible driver for the unit on the USR site and fear that they haven't bothered to write one. Anyone know whether one is available somewhere, or do I need to fling another piece of electric junk in the landfill? System: Quicksilver g4, external USR 56K Sportster faxmodem(#00568902). Unusual aspect of this setup: External Modem is connected to an aftermarket serial port which occupies original internal modem bay - Apple internal modem removed and replaced with g4port serial port to permit use of serial MIDI interface for Hard disk recording of music.
