11.4.3Send Java Security Command to the Module

Use a terminal program. enter:

at^sjsec

wait for the answer:

CONNECT

JSEC READY: SEND COMMAND ...

Now you can send the binary data of the command (for example: from a file with the binary data of the command).

The module’s answer depends on the result of the operation.

The read command, at^sjsec?, can be used to request the current Java security status.
