"Do you want Asynchronous datalink support?"

    If you have installed and configured the VAX WAN Device Drivers
    software on this system, you have the option of configuring it to
    support asynchronous connections.

    Support for asynchronous connections is provided by the VAX WAN
    device driver software. This software gives you the option of
    connecting your OpenVMS system to another system by means of a
    low-cost, low-speed asynchronous line. Asynchronous connections
    are implemented in software and can be run over any directly
    connected terminal line that the OpenVMS system supports. The
    asynchronous protocol provides for a full-duplex connection
    and can be used for remote asynchronous communications over a
    telephone line using a modem.

                                   NOTE

       Asynchronous connections are not supported for maintenance
       operations or for controller loopback testing.

    Normally, the OpenVMS operating system controls lines connected
    to terminal ports, as in interactive login. You can, however,
    switch the line so that the DECnet-Plus for OpenVMS software can
    use the line for an asynchronous connection to another system.
    Refer to the DECnet-Plus Network Management manual for information
    on the OpenVMS DCL SET TERMINAL commands used to switch terminal
    lines to DECnet lines.

    You can establish two types of asynchronous DECnet connections:

    o  A static asynchronous connection, which creates a permanent
       DECnet link to a single remote node. Two nodes are connected
       by either a dialup line or by a physical line attached to
       a terminal port at each end. Before the DECnet connection
       is made, the terminal lines must be converted to static
       asynchronous DDCMP lines.

    o  A dynamic asynchronous connection, which provides a temporary
       DECnet link. This type of line is usually switched on for
       network use only for the duration of a dialup connection
       between two nodes. When the telephone is disconnected, the
       line reverts to being a terminal line. The advantage of
       this type of connection is that you can use a single line
       to establish dynamic connections to different remote nodes at
       different times.

       Also, when creating a dynamic asynchronous connection, you are
       given the option of creating an explicit dynamic connection
       or a floating dynamic connection. The difference is that an
       explicit line is tied to a specific terminal device while a
       floating line is not. When using a dynamic connection, you
       can have the terminal line switched automatically to a DECnet
       line, or you can switch the line manually.

    If you answer YES, the procedure asks the following question:
