How to input these instruments?

[MQi.1]

I tested the example "WiFiBasics" came from STM32CubeIDE on discovery board "B-U585I-IoT02A". The .elf file has been downloaded into board through STM32CubeProg, and when I opened PuTTY as it was told in example's "README", these was prompted:

I just didn't know how to input them - for example: neither of "quit", " quit", and " " quit" " would work, and when I input "Backspace', the characters i have inputted would be shown recursively, when I input "Delete" it would show "]":

is anyone here know why and howto?

the WiFiBasics application expects commands with "\n" (line feed) at the end.

it seems PuTTY only sends "\r" (carriage return). I haven't found a way to configure it to send "\n".

so either use another application (like Tera term) or modify the WiFiBasics sources to accept "\r" for line termination.
