Abstract

In certain word processor applications, there is a need to provide logging of multiple interactive tasks. In particular, when the word processor is connected to a host central processing unit and operated in a data processing mode, it is often important to track operator responses to system messages. Typically, however, there is only one printer available. A problem is therefore presented as to how to track operator keystrokes and system responses on a hard copy printer, preferably with immediate system turnaround. The solution to this problem uses the Echo mode printer access method to allow multiple asynchronous tasks to add data to a FIFO (first-in, first-out) queue of printer work. This is a new use of existing software, and no changes to the printer software are required.

Event Logging on Word Processor Printers

In certain word processor applications, there is a need to provide logging of multiple interactive tasks. In particular, when the word processor is connected to a host central processing unit and operated in a data processing mode, it is often important to track operator responses to system messages. Typically, however, there is only one printer available. A problem is therefore presented as to how to track operator keystrokes and system responses on a hard copy printer, preferably with immediate system turnaround. The solution to this problem uses the Echo mode printer access method to allow multiple asynchronous tasks to add data to a FIFO (first-in, first-out) queue of printer work. This is a new use of existing software, and no changes to the printer software are required. Using this procedure, the responses and messages are printed in FIFO order. Multiple tasks may interleave messages to the printer. There is no fixed format to the messages. The hard copy is available immediately and may be viewed as the events occur in contrast to logs that are printed when the series of events is complete.
