	prompt "Enable console input handler"
	select UART_INTERRUPT_DRIVEN
	default n
	help
	This option enables console input handler allowing to write simple
	interaction between serial console and the OS.

config UART_CONSOLE
	bool
	prompt "Use UART for console"
	default n
	depends on SERIAL && SERIAL_HAS_DRIVER
	select CONSOLE_HAS_DRIVER
	help
	Enable this option to use one UART for console. Make sure
	CONFIG_UART_CONSOLE_INDEX is also set correctly.

config UART_CONSOLE_INDEX
	int "UART Console Index"
	default 0
	depends on UART_CONSOLE
	help
	This option specifies index for the console uart port.

config UART_CONSOLE_BAUDRATE
	int "UART Console Baud Rate"
	default 115200
	depends on UART_CONSOLE
	help

	default 1024
	depends on RAM_CONSOLE
	help
