Question

i’m writing a java code that connects and executes commands in a telnet based equipment.
when i login, appears a message like this:

Trying 10.11.115.160...
Connected to 10.11.115.160.
Escape character is '^]'.

the problem is that when i want logout, don’t know how to write this char ‘^]’ using a simple string, like this:

telnetClient.execute("^]");

or

telnetClient.execute("\uXXXX");

in a linux terminal, it works using ctrl + ].
i don’t found this char in the unicode table.

someone knows? thanks in advance

Ctrl + ] is U+001D INFORMATION SEPARATOR THREE, so it’s \u001d. It can be easily checked by running cat | hexdump and entering Ctrl + ], Ctrl + D.

U+001B ESCAPE is Ctrl + [.
