You can use the NCP Emulator tool to manage remote Phase IV nodes
    with the TELL and SET EXECUTOR NODE commands.  The TELL command
    allows you to perform a single NCP command on the remote node, and
    you may choose to supply access control information within the
    command.  For example, to zero the executor counters on a remote
    Phase IV node from a local Phase V node, enter the following:

    $ run sys$system:ncp
    NCP> tell remnod"account password" zero exec counters

    The NCP Emulator tool is not intended for management of Phase V
    nodes, so all NCP commands are not supported.  The following
    error is returned if an unsupported NCP Emulator command is
    attempted on a Phase V system without specifying a remote
    Phase IV system:

    NCP> zero exec counters
    %NCP-W-SYSMGT, System-specific management function not supported

    When you wish to perform a series of commands on a single remote
    Phase IV node, you can set your default NCP context to that node
    using the NCP SET EXECUTOR NODE command; again you may choose to
    supply default access control information within that command.
    For example, after the following command is issued, all subsequent
    commands within that NCP session will be performed on node
    FAZ4ND using the specified access control information:

    $ mcr ncp
    NCP> set executor node faz4nd"account password"

    information on the use of the NCP Emulator.
