| help |
| This option allows a debug server agent such as GDB to take over the |
| handling of traffic that goes through the console logic. The debug |
| server looks at characters received and decides to handle them itself if |

| Enables the UART console to receive mcumgr frames for image upgrade |
| and device management. When enabled, the UART console does not |
| process mcumgr frames, but it hands them up to a higher level module |

| the module for UART console is in use now. If the interval of console |
| module doesn't receive any input message exceeds expired timeout, such |
| as UART_CONSOLE_INPUT_EXPIRED_TIMEOUT, the power management module is |
| allowed to enter sleep/deep sleep state and turn off the clock of UART |
| console module. This mechanism gives a window in which the users can |
| organize input message if CONFIG_PM is enabled. |
