Configuring Mainframe graphics support

Display settings

  1. Start a BlueZone Mainframe display session.
  2. On the BlueZone menu bar, click Session → Configure.
  3. Click the 3270 Emulation tab.
  4. In the Features group, place a check in all three check boxes:
    • Use Extended Attributes
    • Use Multiple Explicit Partitions
    • Enable Vector Graphics
  5. In the Default Screen Model Type group, select the screen size you are using. Typically, a Model 3 (32x80) screen is used, but other screen sizes can also work.
  6. Click OK.

TN3270E settings

  1. On the On the BlueZone menu bar, click Session → Configure.

  2. Click Properties.

  3. Highlight the desired host in your Connection List.
  4. Click the Device tab.
  5. Select your Device Model and check the Extended Attributes check box. Ensure 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 clear the Override 3270 Emulation Model Type check box.

    This results in BlueZone negotiating the TN3270E connection with the host using the Device Model selected on the TN3270E Properties, Device tab but uses the Default Screen Model Type selected in the Session Configuration, 3270 Emulation tab for the actual screen display.

  6. Click OK twice.

Font settings

  1. On the BlueZone menu bar, click Options → Display. The Font tab is 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 Change and select New Renex Terminal as the font, with 9x12 as the font size.
  3. Click OK.
  4. Clear the Auto-Size Font check box and click OK.
    This forces the terminal session to use a 9x12 font size, which makes the graphics appear the best.
    Note: If a larger size is used, grid lines can appear when scaling raster graphics. If a smaller size is used, graphics detail is lost when scaling down.

Keyboard settings

  1. On the BlueZone menu bar, click Options → Keyboard.
  2. Click the Mouse Options tab.
  3. 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.
  4. Connect to your host and run the graphics application.
