My Bluetooth Serial seems to always be busy.

  • lsof /dev/tty.BluetoothModem yields nothing.
  • sudo chmod 777 /var/lock seemed to have no effect.
  • screen /dev/tty.Bluetooth-Modem tells me it's busy.

I rebooted. I'm using Mountain Lion. How can I possibly debug this?

Apparently, /dev/tty.Bluetooth-Modem isn't the device that I want. I went into the Bluetooth preference pane and selected my device, clicked "Advanced", and added a new software serial device associated with it. I can connect to that one just fine.
