s

<dataForm>(num)

SAP message data format
[0]	XSAP ATC/URC format
	SAP messages are translated into ASCII coded strings and transmitted as
	parameters of AT command AT^SRSM and URC "^SRSM". If using a Bluetooth
	modem with AT command interface for transmitting data, it is recommended to
	choose the XSAP data format. Note that AT commands not related to RSA
	shall not be used after RSA activation on the dedicated serial multiplexer chan-
	nel.
1	SAP transparent binary format
	SAP messages are transmitted as coded in the SAP specification. This data
	format should be selected for transmitting SIM data to a Bluetooth stack which
	is part of the application. The binary data will be exchanged transparently with
	the ME. However, the SAP data format does not need ASCII character conver-
	sation. As a result less data will be transferred and the SIM communication will
	be faster.
<beaconPer>(num)
Beacon period

Determines the period in seconds between sending the CONNECT_REQ messages. A 0 value leads to a one- time connection request. This parameter is applicable for SAP client activation only.

0...[6]...100

<discType>(num)

SAP disconnection type

This parameter is only applicable if <sapRole> equals 0.

Calls or active GPRS contexts via a remote SIM will be lost due to missing SIM access. Use of AT+CLCC is rec- ommended to query call states before RSA deactivation.

0	Hold SAP role
	SAP connection is going to be disabled. The TC63 remains in SAP mode and
	is ready to (re)establish a SAP connection. If a SAP connection was ongoing
	an URC "^SRSA: <devId>, <sapRole>, <connState>" with
	<connState>= 0 is issued.
	• A server exclusively sends a SAP message DISCONNECT_IND (type
	"Graceful") to the client.
	• A client saves SIM data which is temporarily held in TC63's memory to the
	remote SIM and sends SAP message DISCONNECT_REQ to the server. If
	requested the client restarts sending CONNECTION_REQ messages. If a
	local SIM is attached the TC63 will use it to register to the network until a
	server offers its SIM again.
[1]	Stop SAP operation
	SAP connection is disabled and TC63 is forced to local SIM mode. An URC
	"^SRSA: <devId>, <sapRole>, <connState>" with <sapRole>= 0 and
	<connState>= 0 is issued.

• A server sends a SAP message DISCONNECT_IND (type "Immediate") to the client and returns to local SIM mode immediately. SIM data which is temporarily held in client's memory would be lost.

• A client exclusively sends SAP message DISCONNECT_REQ to the server. Without saving temporary held data to a remote SIM or waiting for DISCONNECT_RESP the client returns to local SIM mode immediately.
