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.
