        !            42: .Sh DESCRIPTION
        !            43: .Nm Talkd
        !            44: is the server that notifies a user that someone else wants to
        !            45: initiate a conversation.
        !            46: It acts a repository of invitations, responding to requests
        !            47: by clients wishing to rendezvous to hold a conversation.
        !            48: In normal operation, a client, the caller,
        !            49: initiates a rendezvous by sending a
        !            50: .Tn CTL_MSG
        !            51: to the server of
        !            52: type
        !            53: .Tn LOOK_UP
        !            54: (see
        !            55: .Aq Pa protocols/talkd.h ) .
        !            56: This causes the server to search its invitation
        !            57: tables to check if an invitation currently exists for the caller
        !            58: (to speak to the callee specified in the message).
        !            59: If the lookup fails,
        !            60: the caller then sends an
        !            61: .Tn ANNOUNCE
        !            62: message causing the server to
        !            63: broadcast an announcement on the callee's login ports requesting contact.
        !            64: When the callee responds, the local server uses the
        !            65: recorded invitation to respond with the appropriate rendezvous
        !            66: address and the caller and callee client programs establish a
        !            67: stream connection through which the conversation takes place.
