The Openthread communication with RCP via UART (with HDLC protocol) is performed with serial driver using interrupts. As it was tested with echo_client sample program, the CONFIG_SHELL_BACKEND_SERIAL_API_INTERRUPT_DRIVEN is defined by default for it. This config selects aforementioned UART_INTERRUPT_DRIVEN. Problem starts when somebody wants to integrated the driver as a standalone one (without echo_client) as a part of user application. In this situation the UART_INTERRUPT_DRIVEN is not defined by default and there is no serial communication between RCP and HOST devices. Signed-off-by: Lukasz Majewski <lukma@denx.de>
