ESP32 telnet server catching CTRLC

[Rrobinet]

Hi,

I have a Telnet server running that stops to work when a telnet client sends a CTRL C character.
Is it a way to catch this break character from the client.

The script is in C++ compiled with ARDUINO IDE
Thanks in advance

Well,
This is a stupid question of course.
CTR+[x] is not to handle as an ASCII character (as for normal data entry) but as a string of binary code.
Typically CTRLC sends to the server a hexadecimal string of FFF4FFFD06.
So I did manage to handle these specific strings with my telnet server interactive data entry.
I wonder if this documented somewhere?
