TA selects the procedure for how the receiving of new messages from the network is indicated

Parameters

See Write Command

TA updates the SMSC address, through which mobile originated SMS are transmitted.

In text mode, setting is used by send and writes commands.

In PDU mode, setting is used by the same commands, but only when the length of the SMSC

address coded into <pdu> parameter equals zero.

Note: The Command writes the parameters in NON-VOLATILE memory.

Parameters

<sca>     GSM 04.11 RP SC address Address-Value field in string format(string should be

included in quotation marks); BCD numbers (or GSM default alphabet characters) are converted

to characters of the currently selected TE character set (specified by +CSCS in 3GPP TS 27.007);

type of address given by <tosca>

OK

Parameter

<show>      

0     Do not show header values defined in commands +CSCA and +CSMP

(<sca>,<tosca>,<fo>,<vp>,<pid> and <dcs>) nor

<length>,<toda> or <tooa> in +CMT, +CMGL, +CMGR result codes for SMS-DELIVERs and

SMS-SUBMITs in text mode

+CSMP: <fo>,<vp>,<pid>,<dcs>

OK

Parameters

See Write Command

TA selects values for additional parameters needed when SM is sent to the network or placed in

a storage when text mode is selected (+CMGF=1).

It is possible to set the validity period starting from when the SM is received by the SMSC (<vp>

is in range 0… 255) or define the absolute time of the validity period termination

(<vp> is a string).

Note: The Command writes the parameter <fo> in NON-VOLATILE memory.

OK

Parameters

<fo>     Depending on the command or result code: first octet of GSM 03.40 SMS-DELIVER,

SMS-SUBMIT (default 17),

SMS-STATUS-REPORT, or SMS-COMMAND (default 2) in integer format.

SMS status report is supported under text mode if <fo> is set to 49.

<vp>     Depending on SMS-SUBMIT <fo> setting: GSM 03.40 TP-Validity-Period either in integer

format (default 167) or in time-string format (refer <dt>)

<pid>     GSM 03.40 TP-Protocol-Identifier in integer format (default 0).

<dcs>     GSM 03.38 SMS Data Coding Scheme in Integer format.
