Quite a few of the users of my modem scripts report that their Bluetooth serial port is busy ("Failed to open /dev/cu.Bluetooth-Modem: Device busy") when they try to dial. I then have to get them to hunt about for the application that 'owns' the port, and it is sometimes something really obscure (e.g. fax software that scans every serial port). What simple steps can I use to find the app that has grabbed the port, using just the tools that come with a standard MacOS installation? This email sent to site_archiver@lists.apple.com
