11.3 Application and Data Protection
In addition to the Java secured mode it is possible to prevent the activation of the Module
Exchange Suite. When Module Exchange Suite access is deactivated with at^sjsec, it is no
longer possible to access to the Flash file system on the module.
11.4 Structure and Description of the Java Security Commands
Special commands are used in t he Java security environment. These commands are
transferred to the module with the help of the special AT command at^sjec. This command
makes it possible to send binary data to the module. After at^sjsec is issued, the module
changes into a block transfer mode. Now binary data in a fixed format can be sent. These
binary data contain the actual Java security commands.
