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
|
|
they are some sort of control characters, or let the regular console
|
|
code handle them if they are of no special significance to it.

Enable this option to use the USB UART for console output. The output

can be viewed from the USB host via /dev/ttyACM* port. Note that console

inputs from the USB UART are not functional yet. Also since the USB

selected in conjunction with say USB Mass Storage.

Enable this option to use flow control on the console. The uart console
