Dual paths to the same nodes are detected by the token-ring device manager in one of two ways. First, when a call is in progress to a remote node that is also trying to call the local node, the incoming find (remote name) request is treated as if a local listen were outstanding. Second, when a pending local listen is acquired by a call from a remote node and the local user issues a call to the active remote node, a result code (DLC_REMOTE_CONN) is returned with the link station correlator of the active attachment, allowing the user to relink attachment pointers.
