How to Configure Mainframe Graphics Support

Emulation Settings

Display Settings

1. Start a BlueZone Mainframe display session.

2. On the BlueZone MenuBar, go to Session:Configure, and choose the 3270 Emulation tab.

3. In the Features group, place a check in all three check boxes:

• Use Extended Attributes

• Use Multiple Explicit Partitions

• Enable Vector Graphics

• Enable Programmed Symbols - If you do not want support for Programmed Symbols, un-check this box.

4. In the Default Screen Model Type group, select the screen size you will be using.  Typically, a Model 3 (32x80) screen is used, but other screen sizes may also work.

5. Click the OK button.

TN3270E Settings

1. On the On the BlueZone MenuBar, go to Session:Configure:Configure.  Highlight the desired host in your Connection List.

2. Select the Device tab.

3. Select your Device Model and check the Extended Attributes check box.  Make sure the Override 3270 Emulation Model Type is checked.

NOTE  If your host requires that you connect with a different Device Model type than the one that you need to support graphics, select the Device Model that is required for connection here, and un-check the Override 3270 Emulation Model Type check box.

Result: This will result in BlueZone negotiating the TN3270E connection with the host using the Device Model selected on the TN3270E Properties:Device tab but will use the Default Screen Model Type selected in the Session Configuration:3270 Emulation tab for the actual screen display.

4. Click the OK button two times.

Font Settings

1. On the BlueZone MenuBar, go to Options:Display.  The Font tab, will be used to set the font size.

NOTE  This step is particularly important when using graphics, since the graphics screen emulates an IBM 3179 terminal with a 9x12 character cell.

2. For best results, click the Change button and select New Renex Terminal as the font, with 9x12 as the font size, and click the OK button.

3. Un-check the Auto-Size Font box and click the OK button.

This will force the terminal session to use a 9x12 font size, which will make the graphics appear the best.

NOTE  If a larger size is used, grid lines may appear when scaling raster graphics.  If a smaller size is used, graphics detail will be lost when scaling down.

Keyboard Settings

1. On the BlueZone MenuBar, select Options:Keyboard.  Choose the Mouse Options tab and select Send 3270 Function Enter on Mouse Left Double-Click.

This enables the mouse to be used to select areas on the graphics screen with a double-click and send the graphics cursor location back to the application.

2. Connect to your host and run the graphics application.
