Remote Console Session

      Remote maintenance of complex networks and possibility to
automatically respond to network events is of prime importance as
networks need to operate almost unattended and can be distributed
covering countries.

      The present invention relates to means providing capability of
remote maintenance and automation using plain OS/2* session in which
a remote console session can be used for remote maintenance thru
Public Switched Telephone Network (PSTN) and can used to create
automats.

      The remote console session uses a standard OS/2 Fullscreen
Session (FS) or Window Session (WS) and in the background the remote
console session application is started with different asynchroneous
OS/2 threads.

      The Remote Console application communicates with a Network
Manager application which has access to all the nodes in the network.
The Remote Console application can be in the same hardware unit as
the Network Manager (a PC or a PS/2).

      The Remote Console application monitors unattended alarms
communi cated by the Network Manager application which are
transformed into Generic Alerts and accepts user commands or run
commands (RUNCMDs) to be sent to the Network Manager application.

The Remote Console session can be used in two ways:

1.  Locally at the Network Manager level using the Remote Console
    session user interface,

        At a remote terminal connected via a Public Switched
        Telephone Network (PSTN) to the Network Manager node with IBM
        Distributed Control Access Facility (DCAF) installed to allow
        the remote operator to monitor the Remote Console session
        using the display and keyboard as he was in front of the
        local terminal.

    The Remote Console process includes two threads:

    a.  The main thread which is started by invoking REMCON.EXE
        applica tion either automatically using STARTUP.CMD or
        manually by opening and OS/2 window and invoking REMCON.EXE.

    b.  The child thread which is used to open a secondary session in
        the same OS/2 session.

          As a result, REMCON.EXE operates in the background and
    receives the alarms from the Network Manager application and in
    the foreground the child thread monitors in an OS/2 window the
    operator activity by provid ing a standard OS/2 session interface
    to the operator.

          The operator session can be controlled remotely using DCAF
    to moni tor the Remote Console session thru, for instance, an
    asynchroneous communication port connected thru a PSTN.

          The alarms forwarded to REMCON.EXE are formatted into
    Generic Alerts using a local alert catcher and are used to
    trigger user's com mand list (CLIST) which can be written in OS/2
    REXX or other languages.
