Is there a way to disable flow control in CLI?

I am trying everything.

In sdk_config: #define UART_DEFAULT_CONFIG_HWFC 0 In the nrf_cli_uart.c I changed it to APP_UART_FLOW_CONTROL_DISABLED,

in the pca10040.h I changed the pins to: #define CTS_PIN_NUMBER 0xFF #define RTS_PIN_NUMBER 0xFF

Please help!
