Scenario
The SIM card has sent an
STK proactive command,
but the module does not
unsolicitedly report it to the
CAT client.
AT+CUSATT="<terminal_re
sponse>"
AT+CUSATT="<terminal_re
sponse>"
Issue 02 (2013-09-18)
 STK activation and deactivation still take effect after the device is restarted.
 <proactive_command> and <terminal_response> consist of the full BER-TLV data
object as defined in 3GPP TS 31.111.
 For MU609, STK proactive commands can be divided into three categories:
Category 1: proactive commands that must be processed by the CAT client, including
DISPLAY TEXT, GET INKEY, GET INPUT, PLAY TONE, SELECT ITEM, SET UP MENU,
LANGUAGE NOTIFICATION, and LAUNCH BROWSER.
Category 2: proactive commands processed by the module (the CAT client is still notified),
including SEND SHORT MESSAGE, SEND SS, SEND USSD, SET UP EVENT LIST, and
REFRESH.
Category 3: other proactive commands that are processed by the module (the CAT client is
not notified).
Only commands of categories 1 and 2 are reported using the +CUSATP interface.

 Only terminal responses to commands of category 1 can be delivered using the AT
interface.
