Bluetooth serial is busy 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.
