1    /APPLICATION

    Specifies that a logical port on your node is an application
    port. It can be used to connect to a remote device (typically a
    printer) on a terminal server or to a dedicated port on another
    LAT service node.

    If you do not specify a port type, the default port type is
    APPLICATION.

                                   NOTE

       By default, LATCP creates application LAT devices with
       the HANGUP terminal characteristic. However, if you want
       to apply the NOHANGUP characteristic to application LAT
       devices, you can do so by entering specific LATCP and DCL
       commands. For example:

       $ LCP :== $LATCP
       $ LCP CREATE PORT LTA1234
       $ LCP SET PORT LTA1234 /APPLICATION /NODE=terminal_server /PORT=server_port
       $ SET TERMINAL LTA1234 /PERMANENT /NOHANGUP

       Note that you can insert the SET TERMINAL command in the
       SYS$MANAGER:LAT$SYSTARTUP.COM file (enter the command for
       each LAT device that requires the NOHANGUP characteristic).

2    /DEDICATED

    Specifies that a logical port on your local node is dedicated
    to an application service. When users on a terminal server (or
    on another node that supports outgoing connections) request
    a connection to this service name, they are connected to the
    dedicated port. See the OpenVMS I/O User's Reference Manual for a
    description of programming an application service.

    After creating a dedicated port on a node, use the SET PORT
    /SERVICE command to map this port to a service.

3    /LIMITED

    Specifies that a logical port on your local node is limited to
    a service in the same way a port created using the /DEDICATED
    qualifier is dedicated to an application service. The difference
    is that ports created using the /LIMITED qualifier are under the
    control of the system login image (LOGINOUT.EXE) instead of an
    application program (a user who connects to a limited service and
    is assigned to a limited port receives the "Username:" prompt).

    Using the /LIMITED qualifier, you can create a limited number
    of ports and map them to a specific service offered by the host
    system. If users are logged in to all of the limited ports for
    the service, no more connections are allowed to that service
    (terminal server users receive a "service in use" message).

4    /LOG

       /LOG
       /NOLOG

    Specifies whether LATCP displays a message confirming that
    the port was created. If you do not specify the /LOG or /NOLOG
    qualifier, the default is that no message will be displayed.

5    /LOGICAL

       /LOGICAL=(NAME=logical-name[,TABLE=table][,MODE=mode])

    Specifies a logical name to be associated with the actual name of
    the created port. You must specify a logical name if you do not
    specify a port name.

                                   NOTE

       If you have sufficient privileges to create a port, but lack
       the privilege to assign a logical name, the port will still
       be created.

    You can specify one of the following options for the TABLE
    keyword:

    GROUP      Places the logical name in the group logical name
               table. You must have GRPNAM or SYSPRV privilege to
               place the logical name in the group logical name table.
    JOB        Places the logical name in the jobwide logical name
               table.
    PROCESS    Places the logical name in the process logical name
               table. This is the default.
    SYSTEM     Places the logical name in the system logical name
               table. You must have SYSNAM or SYSPRV privilege to
               place a name in the system logical name table.

    You can also specify the name of a specific table. For example,
    you could specify LNM$PROCESS, which would be the equivalent of
    specifying PROCESS.

    Options for the MODE keyword are:

    EXECUTIVE   Creates an executive mode logical name. You must have
                SYSNAM privilege to create an executive mode logical
                name.
    SUPERVISOR  Creates a supervisor mode logical name.
    USER        Creates a user mode logical name.

    The access mode associated with the logical name is determined
    by maximizing the access mode of the caller with the access mode
    specified by the MODE keyword: the mode with the lower privilege
    is used.

    You cannot specify an access mode with a privilege higher than
    that of the table containing the logical name. However, if your
    process has SYSNAM privilege, then the specified access mode is
    associated with the logical name regardless of the access mode of
    the caller.

    If you omit the MODE keyword, the access mode of the caller is
    associated with the logical name.

    You can also create the port as a limited port, using the
    /LIMITED qualifier.
