Abstract

IBM PC (personal computer) Network users can send messages to other users in the network asynchronously to applications currently executing on the PC. PC Net does not display the message directly. Rather, the user must press a key sequence to enter into an interactive interface to view the incoming message. The IBM PC Network messaging function was used as the basis herefor. This method allows the data to be displayed without the user "hot-keying" to the interactive interface. The user will see the incoming asynchronous data immediately displayed in a "window". The user can then view the message and, by pressing the Esc key, then continue in the application that was interrupted. Once that data has been received, the end user may not be present to respond to the data.

Method for Asynchronous Displaying of Data From S/36 on a PC and Providing Window Timeout Therefor

IBM PC (personal computer) Network users can send messages to other users in the network asynchronously to applications currently executing on the PC. PC Net does not display the message directly. Rather, the user must press a key sequence to enter into an interactive interface to view the incoming message. The IBM PC Network messaging function was used as the basis herefor. This method allows the data to be displayed without the user "hot-keying" to the interactive interface. The user will see the incoming asynchronous data immediately displayed in a "window". The user can then view the message and, by pressing the Esc key, then continue in the application that was interrupted. Once that data has been received, the end user may not be present to respond to the data. Even though the user is not present, an application may be executing that should not be stopped indefinitely. This method allows the continuing execution of the application with the asychronous data still available when the user returns. The above-mentioned message "window" will disappear after a configurable amount of time if the user does not press a key on the PC keyboard. This will allow the application executing to continue. Using the router provided with IBM Support/36, a software application can receive an indication that there is incoming data that has been received by the router. A PC-resident program, as an extension of PC DOS can, based on the timer interrupt, receive this indication. However, due to the restriction of the number of instructions that can execute during a timer interrupt, the data cannot be processed immediately. By hooking the DOS function call and the...
