*
|
|
* If mainSELECTED_APPLICATION = ECHO_CLIENT_DEMO the tcp echo demo will be built.
|
|
* This is implemented and described in main_networking.c

* NOTE: Linux will not be running the FreeRTOS demo threads continuously, so

* do not expect to get real time behaviour from the FreeRTOS Linux port, or
|
|
