1.2. AT Command Set Remote control operation of the GSM mobile telephone runs via a serial interface (data cable of infrared connection), where AT+C commands according to ETSI GSM 07.07 and GSM 07.05 specification as well as several manufacturer specific AT commands are available. These commands are described in more detail later on. The modem guideline V.25ter applies to the sequence of the interface commands. According to this guideline, commands should begin with the character string AT and end with <CR> (= 0x0D). The input of a command is acknowledged by the display of OK or ERROR. A command currently in process is interrupted by each additional character entered. This means that you should not enter the next command until you have received the acknowledgment; otherwise the current command is interrupted. The commands supported are listed in the following tables:

1.2.1. Hayes-Standard Commands The Hayes-standard commands correspond to the commands of AT Hayes-compatible modems.

Command Function

A/ AT. ATA ATD<str>;
Repeat last command Prefix for all other commands Accept call Dial the dialing string <str> with the voice utility Valid dial modifiers: T (tone dialing), P (pulse dialing) is ignored. The character ; is important, for this tells the phone that the call should be set up with the voice utility. Otherwise an attempt is made to set up a data call, which the phone immediately acknowledges with ERROR. The dial command responds with OK to the user right after starting a voide call. Other behavior like *# sequences in the dial command and also data calls remain unchanged. ATD><n>; Dial the telephone number from the current telephone book location number <n> The telephone book is selected with the command at+cpbs (or at^spbs). ATD><mem>< Dial the telephone number from the telephone book <mem> location n>; number <n> ATDL Dial last telephone number ATE0 Deactivate command echo ATE1 Activate command echo ATH[0] Separate connection ATQ0 Display acknowledgments ATQ1 Suppress acknowledgments ATV0 Output acknowledgments as numbers ATV1 Output acknowledgments as text AT&F[0] Reset to factory profile ATZ Set to default configuration AT+GCAP Output the capabilities list

AT Command Set Reference Manual 1.3. AT Commands and Responses According to GSM 07.07 and GSM 07.05 According to GSM, it is possible to execute an AT command in various forms.
Test command AT+CXXX=? The telephone responds by sending the list of parameters and value ranges; these can be set using the affiliated Write command or by means of internal processes. This command tells you the current value setting of the parameter(s). This command is used to set parameters that can be set. The Execute command reads non-settable parameters which are influenced by internal processes in the telephone.

In addition, if there is no FDN phonebook available on the SIM, it is possible to activate a feature which activates FDN-like behavior for the SM and ME phonebooks (FDN replacement). (Currently this feature can only be activated via the MMI lock/device lock/excluding telephone book.) In this case, the Write to the SM and ME phonebooks is ensured by the device code (PH-SIM PIN and PH-SIM PUK, respectively). The sequence for entering the device code is analogous to the above example.

Special hints for using +CPBR/+CPBW command String parameters ,like the <text> in +CPBW command shall be entered using quotation marks `"` ( Ascii=Windows=GSM=0x22).e.g. "Doe Joe" It is possible to enter string parameters without `"` but not recommended, because following problems may occure: If no `"` are used: - SPACEs (Space, Blank, Ascii=Windows=GSM=0x20) are skipped. E.g. at+cpbw=1,"123",,K. H. results in "K.H." L at+cpbw=1,"123",,"K. H." SPACEs are kept J No `,` (Ascii=Windows=GSM=0x2C) and `;` (Ascii=Windows=GSM=0x3B) in <text> is possible, because this characters are used as separator of parameters/commands. E.g. at+cpbw=1,"123",,Kurz,Helmut result in ERROR L at+cpbw=1,"123",,"Kurz,Helmut" J

But there are also some points to note when using quotation marks `"`: There are some characters which cannot be entered in normal way: e.g. quotation mark `"` character itself, because this is interpreted as the end of the <text> To make this (and some other special characters) possible to be entered, the character with hex value 0x5c is used as escape character. In the ASCII character set this is equal the `\` ,like proposed in V.25ter. (Ascii=Windows=0x5C) Unfortunately there is no `\` in GSM character set. The 0x5C equals the `` The escape sequence has the following structure: - The sequence beginns with the escape character 0x5C (ASCII=Windows=`\', GSM=``) - The special character follows and is entered 2 Byte representation of the GSM chacter set value. e.g. the 2 Byte representation of the `@` (GSM=0x00) is `00` Following special characters shall be entered by using the escape sequence:
