What type of network traffic does BlueZone generate on the Web server?
BlueZone uses an ActiveX control or a Java applet which is downloaded only once from the HTTP server, or whenever a new version of the application is installed on the server. This minimizes the amount of network traffic with regard to the download. The session profile is downloaded only once from the HTTP server as well.

For multiple sessions (e.g., 3270 and 5250), multiple session profiles are downloaded from the HTTP server to launch each session.

Traffic to and from the host (3270, 5250, VT100, VT220, SCO ANSI and Wyse 60) is identical to other desktop or Web-based emulators. This traffic can range from light (for users that may access two or three screens per minute) to heavy (for users performing many large file transfers).

Does BlueZone support full 132-column display?
BlueZone does give you the ability to view 132 columns of host information. However, we do recommend using a higher resolution Windows display in order to have the option of using a more readable font - 1024 x 768 is a good place to start. 132-column display is supported in TN3270, TN5250, VT and SCO ANSI terminal emulation.

Does BlueZone support graphics terminal emulation?
Yes, GDDM 3179G graphics and IBM® APA mainframe graphics are supported for the TN3270 emulator, as are IBM Programmed Symbol Sets A-F. In doing so, BlueZone lets you emulate a combination of features found in the older 3279 S3G, 3179G and newer host graphics terminals. Though few mainframe applications incorporate the use of graphics, there are some like SAS/GRAPH from SAS Institute and IBM's GDDM.

Does BlueZone support SSL (Secure Sockets Layer) security for host access?
Yes, SSL is supported as a configuration option in BlueZone. SSL security provides both authentication and encryption to prevent eavesdropping and tampering with your TN3270E, TN5250E, and FTP sessions. In order to use this feature you must be connected to a TN3270E, TN5250E or FTP server that also supports SSL security. If your host does not, Seagull Software’s LegaSuite Security Server can enable you to support an SSL connection without having to upgrade your host.

BlueZone accepts the same Certificate Authorities supported by Microsoft Internet Explorer version 6. BlueZone can also be configured to accept self signed certificates, not yet valid certificates and invalid certificates, if desired.

Does BlueZone support hotspots and are they customizable?
Yes, BlueZone provides the ability to detect certain areas of a screen as a hotspot area. The user can move the mouse to the text and then click or double-click the text to send the appropriate host key back to the host. Hotspots can be made visible or invisible. If visible, the hotspot text will appear similar to a Windows dialog box button to indicate the text is a hotspot.
