Apple OS X Modem Update 1

The Mac OS X Modem Update resolves a rare issue in which a built-in modem cannot dial up. You may see the message: Internet Connect could not open the communications device. After updating or installing Mac OS X 10.2, some Macintosh computers cannot dial out via their built-in modems.

You may see these three symptoms: Internet Connect gives this alert message when you attempt to dial up: Internet Connect could not open the communications device; The Internet Connection Log contains this entry: Failed to open /dev/cu.modem: Device busy; The modem works normally if you start up the computer from Mac OS 9. If you have not experienced the symptoms, you do not need to download the Mac OS X Modem Update. This version is the first release on CNET Download.com.
