Hey !
How to send the console arduino ctrl + z?
Why would you want to do that? The Serial Monitor application has no idea what to do with a Ctrl Z.
ctrl-z is ASCII 26. All the control characters a-z are ASCII 1-26.
Serial.print((char)26);
// or
Serial.write(26);
A bit of history: the control characters were originally about controlling teletype machines. The carrige-return line-feed sequence used to move the print head back to the start of a line and advance the paper feed roller by one line, and so on. Microsoft - for some unfathomable reason - decided to use ctrl-z to mark the end of a text file instead of the more correct ctrl-d (which is what unix uses).
What I'm saying is, sending a ctrl-z to a serial out won't necessarily do what you think it does, unless that serial out is writing to a text file on a windows file system.
Thanks for the clarification.

In the early days, Microsoft did some things like that because they were worried about copyright infringement. The infamous backslash is a prime example.
Ctrl-z predates Microsoft: it was used in Digital Research's CP/M. I'm pretty sure I used it on a DEC PDP too.

Microsoft actually wrote a control-Z in the file at the end. Unix did not store a control-D in the file - control-D was how you generated an end of file signal when typing on a terminal. In Unix, the length of the file was stored in the file's inode, along with other info so that the length of the file could be known even before it was opened.
