Are RFCOMM connections for dialup usually encrypted?

The link is shared across every connection between two devices and this means if you enforce once the encryption it is there for every other RFCOMM, L2CAP etc. connection at that time. Some books don't make this point very clear and talking about a security manager is another topic, because the Bluetooth security mechanism are part of the lower (hardware and firmware) layers.
