Can't close a scpi(telnet) session with echo “^]” when I use it in a script

Question

The use of echo-e \"\\ 029\" does not work either. But if use strg + alt gr + ] directly in a terminal session -> it works.

Answer 1

The ^] means ctrl + right bracket. As strange as that is, it works. You'll be taken to the telnet prompt, where you can type quit.

On international keyboards the ] character is often not a single key, and needs to be replaced with some other key. The correct key is typically the key to the right of P or the next key after that.

Here's a list based on comments below:

Finnish, Swedish, Norwegian, Danish: ctrl + å
French: ctrl + 6
German: ctrl + ü
Swiss: ctrl + ¨
Hungarian: ctrl + 5
Portuguese: ctrl + ´
Dutch, Belgian: ctrl + $
Canadian French: ctrl + ç
