Identifying the Terminal Type to the Diagnostics
Note: This is not the same as selecting a console display.
When you run diagnostics, you must identify what type of terminal you are using. If
the terminal type is not known when the FUNCTION SELECTION menu is displayed,
the diagnostics do not allow you to continue until a terminal is selected from the
DEFINE TERMINAL option menu. Select lft for graphical displays.
Undefined Terminal Types
If you specify an undefined terminal type from the DEFINE TERMINAL option menu,
the menu prompts the user to enter a valid terminal type. The menu is redisplays
until either a valid type is entered or you exit the DEFINE TERMINAL option.
Resetting the Terminal: If you enter a terminal type that is valid (according to
the DEFINE TERMINAL option menu) but is not the correct type for the ASCII
terminal being used, you may be unable to read the screen, use the function keys, or
use the Enter key. These difficulties can be bypassed by pressing Ctrl-C to reset the
terminal. The screen display which results from this reset depends on the mode in
which the system is being run:
Online Normal or Maintenance Mode - The command prompt appears.
Standalone Mode or Online Service Mode -The terminal type is reset to dumb, the
Diagnostic Operating Instruction panel displays, and you are required to go
through the DEFINE TERMINAL process again.
Running Standalone Diagnostics
Consider the following when you run Standalone Diagnostics:
The diagnostic CD must remain in the CD-ROM drive for the entire time that
diagnostics are running.
The diagnostic CD-ROM cannot be ejected from the CD-ROM drive once the
diagnostics have loaded. The CD can only be ejected after the system has been
turned off and then turned on (standalone mode) or after the diagnostics program
has terminated (online concurrent mode).
The CD-ROM drive from which diagnostics were loaded cannot be tested.
The SCSI adapter (or circuitry) controlling the CD-ROM drive from which
diagnostics were loaded cannot be tested.
