Captures data pertaining to a particular port, asynchronous processor board (mux card of a DTC 72MX), DTC, or logical device number and writes it to a disk file.

Security level: 1 for DTC dump; 2 for remaining dump functions.

Syntax

DU[MP]

Description

After the Dump command is entered, the following prompt is printed on the terminal:

     (dump)     Ldev #     POrt #,#,#     SNp  #,#     Mux  #,#     Vc   #,#,#     DTc #     (carriage return to exit) ? 

These are the subcommands that can then be entered. The following pages describe each of these options.

If you press [Return] instead of one of the subcommands, you will be returned to the major prompt and may then enter another TermDSM command.

There are five different types of dump files:

  • Information regarding a particular DTC. This information is written to a disk file in binary form.

  • Information regarding a particular asynchronous processor board in a DTC 72MX.

  • Information regarding a particular logical device number or physical port.

  • Information regarding a particular SNP (X.25) card.

  • Information regarding a particular virtual circuit on an X.25 card.

If you need the information in the dump analyzed, send it to your HP representative on magnetic tape.

Information written to a disk file for this type of dump will appear in two forms:

  • A hexadecimal listing of all data.

  • The ASCII representation of each byte of that data.

The file will also contain:

  • The day and time of the dump.

  • The type of dump (logical device number or port).

  • Headings before each of the major areas of dump information.

If a dump file for an ldev number or port is to be printed, a printer file equation with the CCTL option should be used. In the following example, TRM123AB is the name of the dump file:

     :FILE LIST;DEV=LP;CCTL     :PRINT TRM123AB.PUB.SYS,*LIST 
NOTE: Complete information describing the situation that necessitated the use of DUMP is invaluable in assisting the HP representative's analysis of TermDSM dumps. You may use the COMMENT command to help document the situation.
