   14  *
   15  * @ref le_atServer_interface.h "API Reference"
   16  *
   17  * The AT commands Server handles AT commands' subscriptions on a requested serial device. The
   18  * server is compliant with 3GPP 27.007, paragraphs 4.0, 4.1 and 4.2, and V25 ter, paragraphs 5.3,
   19  * 5.4.
   20  *
   21  * @section le_atServer_binding IPC interfaces binding
   22  *
   23  * All the functions of this API are provided by the @b atService.
   24  *
   25  * Here's a code sample binding to the AT commands server:
   26  * @verbatim
   27    bindings:
   28    {
   29      atServerTest.atServerTestComp.le_atServer -> atService.le_atServer
   30    }
   31    @endverbatim
   32  *
   33  * @section atServer_syntax AT command syntax
   34  *
   35  * @subsection atServer_Syntax Syntax rules
   36  *
   37  * To be interpreted, the command line sent to the AT commands server must start by the pattern
   38  * "AT" (mean ATtention command).<br>
   39  * Lowercase characters are changed to their uppercase equivalents. Only characters between quotes
   40  * are not replaced.
   41  *
   42  * The supported command formats are:
   43  * - Basic syntax command:
   44  *      - using the format AT<command>[<number>]<br>
   45  * The command name is composed of one or several of those characters: A to Z, & and \\.
   46  *      - the syntax of S command is also supported, like:
   47  *          - ATS<parameter_number>?
   48  *          - ATS<parameter_number>=<value>
   49  *      - D command is supported. The characters which don't belong to the following list are
   50  * ignore:
   51  *              - V.250 dialing digits: 0 1 2 3 4 5 6 7 8 9 * # + A B C D
   52  *              - V.250 modifier characters: , T P ! W @
   53  *              - V.250 semicolon character: ;
   54  *              - GSM/UMTS modifier characters:
   55  *                  - I or i for CLIR supplementary service subscription
   56  * (I=invocation, i=suppression)
   57  *                  - G or g for CUG supplementary service subscription (G=invocation,
   58  * g=suppression)
   59  *                  - Direct dialing from phonebook: > (if follow by a string, it has to be put
   60  * between quote)
   61  *              .
   62  * @if 0 doxygen comment: The dot above ends the sub item, and must be kept @endif
   63  * All characters after the "D" are considered part of The D command parameter up to a semicolon or
   64  * the end of command line.
   65  * <br>
   66  * - Extended command format, with the following format:
   67  *      - action command with no parameters: AT+<name>
   68  *      - parameter command: AT+<name>=<value1>[,<value2>[,<value3>[...]]]<br>
   69  *        Values must be separated by a coma. Some values may be optional: in that case, optional
   70  *        value can be omitted in the AT command (e.g. AT+ABCD=,1).<br>
   71  *        A value is a string composed of one or several of the following characters: 0 to 9,
   72  *        A to F, H, z*, #, +, -. To set a value with other characters, the value has to be set
   73  * between quote.
   74  *      - test command (determine the supported values): AT+<name>=?
   75  *      - read command (determine the current values, or stored values): AT+<name>?
   76  *
   77  * @note '+' AT command starting character shall be replaced by other symbol, not included into
   78  * a to z, A to Z, & and \\.
   79  *
   80  * @subsection atServer_concate Concatenating commands
   81  *
   82  * Basic syntax command can be concatenated without a separator:<br>
   83  * ATE1V1S95=47S0=0
   84  *
   85  * Additional commands (extended syntax command or basic syntax command) can be added after an
   86  * extended syntax command with the insertion of a semicolon at the end of the command:<br>
   87  * AT+CMDA=<param1>,<param2>;+CMDB?;+CMDC=?<br>
   88  * AT+CMDA=<param1>,<param2>;E1V1
   89  *
   90  * Extended syntax command can be concatenated after basic syntax commands without a separator:<br>
   91  * ATE1V1+CMD=<param1>
   92  *
   93  * @section atServer_binding Device Binding
   94  *
   95  * le_atServer_Start() must be called to bind the file descriptor of the device with the AT commands
   96  * server. Note that a socket can also be bound.
   97  * Multiple devices can be bound.
   98  * A file descriptor can be unbound using le_atServer_Stop().
   99  *
  100  * The server can be suspended using le_atServer_Suspend() in order to use the
  101  * opened fd for other purposes like starting a PPP service on the opened fd.
  102  * For that a fd dup needs to be done before opening a server session.
  103  * When needed, the server can be resumed using le_atServer_Resume(). Make sure
  104  * to close the fd when the application exists or you may get too many open files error.
  105  *
  106  * used before opening a server session
  107  * @section atServer_subscription Subscription
  108  *
  109  * A new AT command can be added into the parser using le_atServer_Create(), and it can be deleted
  110  * using le_atServer_Delete().
  111  * le_atServer_EnableEcho() allows the user to enable echo on a selected device.
  112  * le_atServer_DisableEcho() allows the user to disable echo on a selected device.
  113  *
  114  * le_atServer_EnableExtendedErrorCodes() allows the user to use extended error
  115  * codes on a selected device.
  116  * le_atServer_DisableExtendedErrorCodes() allows the user to disable extended
  117  * error codes on a selected device.
  118  *
  119  * @section atServer_handler Handler
  120  *
  121  * To handle the AT command, the application has to subscribe a handler using
  122  * le_atServer_AddCommandHandler(). It can be removed with le_atServer_RemoveCommandHandler().<br>
  123  * The called handler (le_atServer_CommandHandlerRef_t prototype) can use
  124  * le_atServer_GetCommandName() to retrieve the received AT command string.<br>
  125  * The device used to execute the AT command can be retrieve thanks to le_atServer_GetDevice().<br>
  126  * It can also call le_atServer_GetParameter() to retrieve parameters of the AT command. This
  127  * function gets the string sending through the AT command. If the parameter was sent between
  128  * quotes, the quotes are removed. This API can be used for both formats:
  129  * - In case of a basic format command, if exists, the parameter can be retrieved at the index 0.<br>
  130  * For S command specific format (ATS<parameter_number>=<value>), the <parameter_number> is
  131  * retrieved at the index 0, the <value> parameter at the index 1.
  132  *
  133  * - In case of an extended format command, parameters are retrieved thanks to their indexes,
  134  * starting from 0. If the parameter is missed (e.g. "AT+CMD=,1"), the getting value is an empty
  135  * string (i.e. '\0' with null length).
  136  *
  137  * The handler receives in argument the type of the AT command (of le_atServer_Type_t type).
  138  * Even if these types are specific to the extended format commands according to the standards, they
  139  * are also applicable here to basic format commands to detect commands with parameters, or read
  140  * values (e.g. ATS<parameter_number>?).
  141  *
  142  * @section atServer_responses Responses
  143  *
  144  * @subsection intermediateRsp Intermediate response
  145  *
  146  * The application has can send intermediate responses through
  147  * le_atServer_SendIntermediateResponse().
  148  *
  149  * @subsection finalRsp Final response
  150  *
  151  * In all cases, the application must send a final response using
  152  * le_atServer_SendFinalResponse(). The corresponding device will be locked until the final response
  153  * is sent.
  154  *
  155  * If no answer is sent, the device will not accept any new AT commands (an error will be
  156  * returned).
  157  *
  158  * le_atServer_SendFinalResponse() has to inform of the result thanks to the argument of
  159  * le_atServer_FinalRsp_t type. This argument permits to the AT command Server to:
  160  * - create the result string if no custom string is provided
  161  * - continue or stop the parsing of concatenated commands: if one command is failed, next commands
  162  * are not executed, the final result of the concatenated AT command is the last error.
  163  *
  164  * @subsection unsolicitedRsp Unsolicited response
  165  *
  166  * The application can also send unsolicited responses to warn a host
  167  * application using le_atServer_SendUnsolicitedResponse().
  168  *
  169  * This response is sent when no AT command is being processing on the device (i.e. unsolicited
  170  * response is sent between the latest final response and the next reception of an AT command).<br>
  171  * If an unsolicited response is sent when an AT command is in progress, the unsolicited response
  172  * is buffered and sent as soon as the device becomes available (i.e., the processing AT command
  173  * sends its final response).
  174  *
  175  * @section Text
  176  *
  177  * le_atServer_GetTextAsync() allows the user to register a le_atServer_GetTextCallback_t callback
  178  * to retrieve text and sends a prompt <CR><LF><greater_than><SPACE> on the current command's
  179  * device.
  180  *
  181  * It will receive at max LE_ATDEFS_TEXT_MAX_LEN bytes.
  182  * If Esc Key is hit then the command is canceled and an empty buffer is returned with result
  183  * set to LE_OK.
  184  * If Ctrl+z is hit then the received buffer is returned and the result is set to LE_OK.
  185  * In case of a read error, an empty buffer is returned with result set to LE_IO_ERROR;
  186  *
  187  * Example:
  188  *
  189  * AT+CMGS="+85291234567"
  190  * > <ESC>
  191  *
  192  * OK
  193  *
  194  * AT+CMGS="+85291234567"
  195  * > It is easy to send text messages. <CTRL-Z>
  196  * +CMGS: 5
  197  *
  198  * OK
  199  *
  200  * @section atServer_bridge Bridge
  201  *
  202  * A second file descriptor can be used thanks to le_atServer_OpenBridge() to send
  203  * all unknown AT commands to an altervative device (such as the modem). For all devices linked to
  204  * that bridge using le_atServer_AddDeviceToBridge(), unknown commands will be sent through that file
  205  * descriptor.
  206  *
  207  * @image html atCommandsParserBridge.png
  208  *
  209  * @note AT commands server is opened on the file descriptor fd1 using le_atServer_Open() API.
  210  * AT commands server is bridged on the file descriptor fd2 using le_atServer_OpenBridge() API.
  211  *
  212  * A device can be remove from a bridge thanks to le_atServer_RemoveDeviceFromBridge() API.
  213  * A bridge can be closed using le_atServer_CloseBridge() API.
  214  *
  215  * @warning Some modem AT commands may conflict with Legato APIs; using both may cause problems that
  216  * can be difficult to diagnose. The modem AT commands should be avoided whenever possible, and
  217  * should only be used with great care.
  218  *
  219  * The application can send an unsolicited on all opened device, or only one on a dedicated deivce.
