Abstract

A method is described to enhance the Displaywriter Link Analysis Procedures to eliminate the need of the 'Communication Link Problem Determination Guide(s)' and increase the overall effectiveness of the package at the same time. The new procedure is also adaptable to other machines. Link Analysis identifies why two machines cannot communicate. Examples of things that can cause machines not to communicate are: faulty modems, incorrect application setup, noisy lines, faulty business machine hardware, etc. Link Analysis tools include Link Analysis Utilities which test and exercise the communication facilities, modem test which tests the modem, line, etc., and Link Analysis procedures which direct the use of the Link Analysis Utilities and modem test.

Automated Link Analysis for Displaywriter

A method is described to enhance the Displaywriter Link Analysis Procedures to eliminate the need of the 'Communication Link Problem Determination Guide(s)' and increase the overall effectiveness of the package at the same time. The new procedure is also adaptable to other machines. Link Analysis identifies why two machines cannot communicate. Examples of things that can cause machines not to communicate are: faulty modems, incorrect application setup, noisy lines, faulty business machine hardware, etc. Link Analysis tools include Link Analysis Utilities which test and exercise the communication facilities, modem test which tests the modem, line, etc., and Link Analysis procedures which direct the use of the Link Analysis Utilities and modem test. The Displaywriter Link Analysis package consists of a Communication Link Problem Determination Guide (CLPDG) for each protocol, a Link Analysis Diskette (LAD) which contains Link Analysis Utilities, a personalization worksheet for each task, progress worksheets, and modem tests provided by the modem manufacturers. The Displaywriter CLPDG directs the user through the procedures required to determine a link problem. The procedures include performing tests, answering questions, filling out a Progress Worksheet, and following arrows and go-to statements. Although Displaywriter keeps an extensive communication error log, the communication error log is not fully realized since the existing CLPDG never uses the error log data. The Automated Link Analysis procedures enhance the current Displaywriter Link Analysis procedures as follows: * By providing Error Log Analysis. Problems are identified more quickly and effectively by the elimination of unnecessary steps. In some cases, the problem can be identified from the error log without any additional testing. * By eliminating the CLPDG. Instructions and questions are placed on the machine, thus making the machine interactive with the user. By placing the CLPDG on the machine several benefits are obtained. The benefits are: - The routine can branch to the next step without relying on the user to follow arrows or go-to statements. Provisions are provided so that the user can skip back to the preceding step(s). - The size of the document cannot intimidate the user, since there is no document. - Updates and corrections can be done more quickly and easily. - There is no need for user updated progress charts since the information can be kept in RAM (random-access memory). The Automated Link Analysis procedure for Displaywriter requires that a Memory Record Diskette (MRD), taken at the time of the problem, be available before the procedure can be started. A MRD is a dump of Displaywriter's RAM. Also, the base Displaywriter Problem Determination Procedures (PDP) must have been completed to ensure that no solid problems exist on Displaywriter. An overview of the Displaywriter Automated Link Analysis procedure is as...
