The Point-to-Point Protocol utility (PPPD) allows you to initiate
    and control a Point-to-Point Protocol (PPP)-compliant network
    connection from an OpenVMS Alpha host and define its physical
    link parameters.
    Specifically, you can use this utility to:
    o  Create an asynchronous (ASN) device. PPPD creates the device
       automatically if one is not currently associated with a serial
       port (such as TTA1).
    o  Set both PPP and ASN device characteristics such as flow
       control and baud rate.
    o  Inform the network stacks that there is a new physical
       transport that uses the PPP.
    o  Act as a simple terminal emulator when establishing a
       connection to a new system (asynchronous only).
    o  Display configuration information about the ASN and PPP device
       drivers as well as any ongoing PPPD sessions.
    Format
      $ PPPD
    The utility then displays the following prompt:
    PPPD>
    After invoking PPPD, you can perform PPPD operations by entering
    the appropriate commands. You can also enter a single PPPD
    command on the same line as the command that invokes the utility,
    for example:
    $ PPPD CONNECT TTAO:
    To exit from the Point-to-Point Protocol utility, enter the
    EXIT command at the PPPD> prompt or press Ctrl/Z. Either method
    returns control to the DCL command level.
    For information about the PPPD utility, enter the HELP command at
    the PPPD> prompt.
