What does RFCOMM bind do?

This binds the RFCOMM device to a remote Bluetooth device. The command did not establish a connection to the remote device, it only creates the binding. The connection will be established right after an application tries to open the RFCOMM device. If no channel number is specified, it uses the channel number 1.
