ABSTRACT:
An information processing system continues communication without affecting the operation of an application when a communication line is disconnected due to a communication error. When the application sends a communication connection request to another system, an MS Manager portion connects the application via a communication line. An MS portion sends a control handle, instead of a communication line handle, to the application. When the application sends data, the MS portion changes the control handle appended to the data to the handle of the actual communication line. When data is received from another system, the MS portion changes the handle of the actual communication line to the control handle and passes the control handle to the application. When the communication line is disconnected due to an error, the MS Manager portion connects the application to the other system via another communication line. The MS portion re-sends data not yet received by the other system if there are any.
