   13  * @page c_port Port Service
   14  *
   15  * @ref le_port_interface.h "API Reference"
   16  *
   17  * This service manages a list of serial links (physical or emulated). It also manages the
   18  * link modes (AT command and data mode).
   19  *
   20  * @section le_port_binding IPC interfaces binding
   21  *
   22  * All the functions of this API are provided by the @b portService.
   23  *
   24  * Here's a code sample binding to the port service:
   25  * @verbatim
   26    bindings:
   27    {
   28       portTest.portTestComp.le_port -> portService.le_port
   29    }
   30    @endverbatim
   31  *
   32  * @section port_request Request Device
   33  *
   34  * le_port_Request() must be called to open a configured device. If the device was not opened, it
   35  * opens the device.
   36  *
   37  * @section port_SwitchMode Switch Mode
   38  *
   39  * le_port_SetDataMode() must be called to switch the device into data mode.
   40  * le_port_SetCommandMode() must be called to switch the device into command mode.
   41  *
   42  * @section port_Release Release Device
   43  *
   44  * le_port_Release() must be called to release the device.
   45  *
   46  * @section port_config Configuration
   47  *
   48  * @todo Configuration documentation to be written.
   49  *
   50  * @section port_GetPortReference Get Port Reference
   51  *
   52  * le_port_GetPortReference() must be called to get the port object reference regarding to a given
   53  * reference coming from the AT server.
   54  *
   55  * @todo The port service is not implemented yet.
