Abstract

The Link Test System (LTS) and the Multi-Simulator Control Unit (MSCU) are driven by several diskettes. A method is provided for changing the codes of these diskettes, without re-writing the diskettes, in the following procedure. (Image Omitted) When the Link Procedure Language Operating System (LPL/OS) is loaded and controls the processing environment, the LPL procedures are executed to check the diskette level in the order seen in Fig. 1. Because the MSCUs are set up for cells 0 and 1 on the first and cells 2 and 3 on the second, a Universal Controller Model 5 (UC.5) diskette is checked along with the first cell on each MSCU. When cell zero (0) of a quadrant is initialized in the LPL/OS bring up, as in Fig. 1, the program $DSKUC51 will be executed to check and update the UC.5 number one (1) diskette, if necessary.

Link Test System/Multi-Simulator Control Unit Autowrite

The Link Test System (LTS) and the Multi-Simulator Control Unit (MSCU) are driven by several diskettes. A method is provided for changing the codes of these diskettes, without re-writing the diskettes, in the following procedure.

(Image Omitted)

When the Link Procedure Language Operating System (LPL/OS) is loaded and controls the processing environment, the LPL procedures are executed to check the diskette level in the order seen in Fig. 1. Because the MSCUs are set up for cells 0 and 1 on the first and cells 2 and 3 on the second, a Universal Controller Model 5 (UC.5) diskette is checked along with the first cell on each MSCU. When cell zero (0) of a quadrant is initialized in the LPL/OS bring up, as in Fig. 1, the program $DSKUC51 will be executed to check and update the UC.5 number one
(1) diskette, if necessary. This diskette will be written in the UC.5 number 1 diskette drive of the LTS. If there is no change in the EC level required, the procedure exits immediately. The procedure flow for $DSKUC51 is seen in Fig.
3.

(Image Omitted)

When cell two (2) of a quadrant is initialized in the LPL/OS bring up, as in Fig. 1, the program $DSKUC52 will be executed to check and update the UC.5 number two (2) diskette, if necessary. This diskette will be writen in the UC.5 number 2 diskette drive of the LTS. There is no special intervention required by the person loading the LTS. If there is no change in the EC leve...
