Troubleshooting
Problem
This document describes how to access 5250 control functions and key sequences on the HMC 5250 emulator.
Resolving The Problem
The HMC 5250 console function uses the 5250 emulator from the IBM iSeries Access for Linux product. Emulator documentation is available on the HMC by using the Help menu option on the emulator or the setup panel. A PDF file is available at the following iSeries InfoCenter site:
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/rzatv/rzatv.pdf
Control Functions
Control functions are available from the 5250 emulation session Control menu. To send a control key, click the Control menu, then select any of the following keys:
o Reset key
o System Request Key (SysRq, also commonly known at the sysreq key)
o Attention Key
o Help Key
o Enter Key
The control functions can also be accessed by using a key sequence.
Default Key Sequences
The default key sequences can be viewed by clicking the Help menu and selecting the Key Sequences topic. The current keyboard mappings can also be viewed by clicking on Option > Keyboard Remapping. Some examples follow:
Attention: Esc
Copy to clipboard: Shift + left-click (click and drag to select, release to copy)
Paste from clipboard: Shift + right-click
Note: On the HMC, the Print Screen, Scroll Lock, and Pause/Break keys are reserved for the window manager. All default mappings using those keys are disabled. This includes the default mapping for the System Request Key (Alt+Print Screen).
Keyboard Remapping
The 5250 emulator keyboard mapping can be customized. To change or view the current mappings, you should do the following:
| 1. | Start a 5250 emulation session. |
| 2. | Click on the menu item Option > Keyboard Remappings. If the menu item is missing or disabled (grayed out) then verify that it is enabled in the IBM 5250 Setup panel. The setup panel can be launched by doing the following: a. Right-click on the desktop and select Terminals > IBM5250. b. In the 5250 Setup panel, click Preferences > 5250. c. Verify the keyboard mapping setting is enabled. |
| 3. | The Keyboard Remappings panel can be used to change the default mappings. For example, the system request can be mapped to Shift + Print Screen. |
| 4. | Click the Apply changes to session button to apply the changes to the current emulation session. |
| 5. | Click the Save button to save the changes. The user can select to save the changes as the new mapping for all user sessions or for this emulation session only. The changes are scoped to the current HMC user profile. |
The HMC remote 5250 console function allows other emulators to be used. If a user has already created customized macros, keypads, keyboard mappings, and so on for another emulator, it might be easier to use that emulator over a remote 5250 console than to re-create the customization on the HMC.
