3.5 Using Menus and Dialog Boxes

After the 3270 emulation program starts, one of the following is displayed:

If you see the main screen instead of a session, then you do not have any 3270 sessions set to be enabled at initialization. For instructions on updating your style file to enable a session at initialization, refer to Customizing Display Sessions.

In the Motif emulation program, the 3270 display appears as part of the main screen (with the menu bar at the top). If you do not have an enabled or active session, the main screen is displayed, but the area where the 3270 display would appear is blank.

If you have more than one active session, each session appears in a separate window as a separate main screen with its own menu bar. You can customize the title for each window to help distinguish between them; for more information, see Customizing Display Sessions.

A typical 3270 display is shown in Sample 3270 Display.

3.5.1 Displaying the Main Screen

From a 3270 display session, you can move to the main screen at any time to gain access to the File, Customize, or Control pull-down menus. You can use them to customize and control 3270 emulation. To move from a 3270 display to the main screen, press ACTIONS (default keystroke Ctrl + U). The main screen is shown in Changing from a 3270 Display to the Main Screen.

Changing from a 3270 Display to the Main Screen

The name of the style file also appears near the top of the main screen. To return from the main screen to 3270 emulation, press Esc, or choose Return to Emulator under the File menu.

In the Motif emulation program, the 3270 display appears as part of the main screen (with the menu bar at the top); you can access the menus at any time. However, if you have more than one active session, you can access the menus in only one session window at any time. When you pull down a menu or move to a dialog box in one window, the menu bars in all other 3270 emulation session windows are disabled until you end all menus and dialog boxes in the first window.

3.5.2 Incorrect Style File Specified

If the style file name you specify is incorrect, or the file is not valid or cannot be opened, a message similar to that shown in Incorrect Style File Message, appears on the main screen when the program starts.

Incorrect Style File Message

Choose <Exit Message> to acknowledge the message. You can then attempt to open the correct file using the File menu. For more information, see Customizing 3270 Emulation. Alternatively, you can continue with 3270 emulation without using a style file, in which case, you will use the program's default style.

3.5.3 Using Style Files and Customizing Emulation

A style file contains the parameters that control the appearance and behavior of your terminal in 3270 emulation.

Using the File menu, you can take the following actions:

You can use the Customize menu, to change customization parameters, which you then save to a style file. However, you will not be able to modify the default style or open new style files if your System Administrator has not given you permission to do this. For more information about complete instructions for using style files, see Customizing 3270 Emulation.

3.5.4 Controlling Emulation

You use the Control menu to control emulation-enabling and disabling 3270 display sessions and 3287 printer sessions, starting and stopping file transfers, and viewing host response times. For instructions, see Controlling 3270 Emulation.

3.5.5 Communicating with the Host

To conduct 3270 emulation, do the following:

  1. Log on to a host (if required to do so) and communicate with its control and application programs through an active session.

  2. Move to the currently selected session by choosing Return to Emulator under the File menu or by pressing the Esc key.

  3. Switch to another active session if desired, and follow the host computer's logon instructions, if any.

For instructions for moving from the 3270 emulation program to 3270 sessions and from one session to another, see Controlling 3270 Emulation.

3.5.6 Moving between a 3270 Session and the Main Screen

To return temporarily from a 3270 display session to the main screen, press ACTIONS (default keystroke Ctrl + U).

To resume 3270 emulation from the main screen, press Esc.

In the Motif emulation program, the 3270 display appears as part of the main screen (with the menu bar at the top); you can access the menus at any time. However, if you have more than one active session, you can access the menus in only one session window at any time. When you pull down a menu or move to a dialog box in one window, the menu bars in all other 3270 emulation session windows are disabled until you end all menus and dialog boxes in the first window.

3.5.7 Temporary Exit to the Solaris Command Prompt

To move temporarily from a 3270 display session to a command prompt for Solaris, leaving the 3270 emulation program running, press TEMPEXIT (default keystroke Ctrl + Z). This starts a new Solaris shell of the type specified by the SHELL environment variable (the default is /bin/sh). You could use this feature, for example, to do any of the following tasks:

To resume 3270 emulation from a temporary exit, use the Solaris end-of-file (EOF) key sequence for your terminal (typically Ctrl + D).

The TEMPEXIT keystroke is not supported in the Motif 3270 emulation program. Instead, you can move to a new terminal window using the mouse as usual.

3.5.8 Ending Emulation

When you have finished using 3270 emulation and want to exit to the Solaris command prompt, take these steps:

  1. Log off the host system (for each active 3270 display session).

  2. Press ACTIONS (default keystroke Ctrl + U) to display the main screen.

    This step is not required in the Motif program.

  3. From the File menu, choose Exit .

    As an alternative to steps 2 and 3, or if you started 3270 emulation using the option, you can press EXIT (default keystroke Ctrl + X) to exit the program.
