* With small example code in master.
* esp_connect currently blocks the execution.
* Debug messages in socket don't follow the standart.
(It is .c file, while debug messages are done in c++)
* LpcUart will work only with UART1, due to the PIN_FUNC.
* Refactored LpcUart for USART0, the handling is a bit different,
so it would have been painful to add that to LpcUart class.
* scanf() still doesn't work, but hey, we have debug prints now!
* Can't believe it actually worked.
