invention relates to means providing capability of

a remote console session can be used for remote maintenance thru
Public Switched Telephone Network (PSTN) and can used to create
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
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).
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
The Remote Console process includes two threads:
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.
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.
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.
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.
