> 12.4 | Structure and Description of the Java Security Commands

> Special commands are used in the Java security environment. These commands are transferred to the module with the help of the special AT command AT^SJSEC. 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.
