IBM 3153 ASCII Terminal Display - Setup values not being saved or losing setup values

Applicable to: World-Wide

Symptom:
The 3153 is not saving setup values or looses it setup values or changes its setup values:

Background Information:
There are several causes for a 3153 losing, not saving or changing its setup values.

Host Operating System/Application (Change Setup Commands):
The host operating system or the host application can change most of the 3153 setup values by sending commands (IBM 3151, WYSE, DEC emulation) that change a 3153 setup value. These commands change the operation of the 3153.

The following are some examples:
IBM 3151 Emulation:
- Set Control 2 Cmd: CRT Saver, Enter Key, New Line
- Set Control 3 Cmd: Scroll, Line Wrap, Insert Character
- Set Control 4 Cmd: Send Line, Send Page
- Set Control 5 Cmd: Turnaround Character, Line Control
- Set Column Tab Cmd: Tabs
- Create Viewport Cmd: Rows and columns
- Set Cursor Type Cmd: Cursor Style
- Set Default Function Key Cmd: Resets Function Keys

WYSE Emulation:
- Enhance Mode Cmd: Enhance Mode
- Communication Cmd: Communication Mode
- Application Key Mode Cmd: Application Mode
- Scrolling Speed Cmd: Scroll
- Display Cursor Cmd: Cursor Style
- DEC Emulation:
- Set Terminal Mode Cmd: Auto Wrap, Scroll, Numeric Keypad
- Tab Set Cmd: Tabs

Persons must know what the host operating system, host application is controlling.

Host Operating System/Application (Terminal Reset Commands):
The host operating system or the host application can reset the 3153 by sending the appropiate emulation reset command.

IBM 3151 Emulation:
- Reset to Initial State Command: Causes 3153 to reset to power on values.

DEC Emulation:
- Terminal Reset Command: Causes 3153 to reset to power on values.

Persons must know what the host operating system, host application is controlling.

3153 Setup Menus:
The user changes parameters in the 3153 setup menus, but does perform the 'save'. When the 3153 is powered off then on, the parameters have not been saved.

Recommended Solution:
Determine if Host Operating System/Application is changing the 3153 setup values. Do the following steps:
1. Set the 3153 setup parameters as needed.
2. Perform 3153 setup parameters save operation.
3. Power off 3153.
4. Power On 3153.
5. Confirm that the setup values have been properly saved. (This step confirms that a 'save' function was properly performed).
6. Begin/Start the host application.
7. Periodically check 3153 setup parameters.

If all the steps are followed, and sometime during step 7 a 3153 setup value is changed, the host operating system or application is changing the 3153 setup values. Persons should check with their systems administrator, systems programmer.

Notes:
For programming information on the 3151 and 3153, refer to 3151 Programmers Reference Manual (GA18-2634) 3153 Programmers Reference Manual (GC30-3707.) Programmer Reference manuals are designed for programmers and
application developers.
