Abstract

A method is described which provides specific diagnostic information indicating the machine status of a remote workstation under local operator control. Communications networks link multiple workstations. Problem diagnosis in a network environment can involve a failure due to any of the workstations. Failures can be analyzed locally; however, the capability to determine the status of a remote workstation is generally unavailable. One can obtain the reactions to a given scenario by viewing a line monitor of the network protocol. The line monitor does not provide the specific workstation status to isolate a problem. By having both the local and remote workstation status at a single workstation, problem determination is greatly enhanced.

Remotely Controlled Diagnostic Interface

A method is described which provides specific diagnostic information indicating the machine status of a remote workstation under local operator control. Communications networks link multiple workstations. Problem diagnosis in a network environment can involve a failure due to any of the workstations. Failures can be analyzed locally; however, the capability to determine the status of a remote workstation is generally unavailable. One can obtain the reactions to a given scenario by viewing a line monitor of the network protocol.

The line monitor does not provide the specific workstation status to isolate a problem. By having both the local and remote workstation status at a single workstation, problem determination is greatly enhanced. In accordance with the new method, an application program is provided for the remote workstation that interprets a set of control sequences transmitted from the local workstation. These control sequences specify special diagnostic Application Program Interface (API) commands to be executed at the remote workstation. The subsequent network protocols and related API status generated at the remote workstation are returned as diagnostic information to the local workstation, allowing problem determination to be performed at the local workstation. The method provides a mechanism for returning diagnostic information from a remote workstation under the control of the local operator. Without this capa...
