ANSI output in Serial Monitor

Development Tools IDE 2.x
1

hello i new in arduino and my english is not good but i will try my best to tell you. I dont know why but when i use a ANSI library with my esp32 board and upload a example in libary of this code to a board and see a serial monitor i think it not a correct output but i dont know why. can someone help me to fix it or it is normal output? (I will show output and code below)
This is a output in serial monitor

Welcome to the forum

The Serial monitor of the IDE does not support ANSI control codes. If you want to use such codes then you can use an external terminal emulator

3

Examples of ANSI terminal programs (windows) are TERATERM or PUTTY.

Remember that not all ANSI terminals are created equal so it might that not all commands are supported. What platform / PC do you use? Windows Mac Linux other?

Version 0.3.5 is the latest, please have a look at ANSI/supportMatrix.md at master · RobTillaart/ANSI · GitHub
to see what commands are expect to work.

Now I see it... in another reference... ESC[2J erase entire screen

[disregard this...]
Perhaps I am not reading this right, referring to ansi.cpp... I thought the escape sequence on Vt52, VT100 and VT220 for:

  • "HOME" was ESC[H and
  • "CLRSCR" was ESC[J

... as opposed to CLRSCR in the file showing HOME, CLRSCR

  _stream->write("\033[", 2);
  print(clear);
  _stream->write('K');
}

void ANSI::home()
{
  _stream->write("\033[H", 3);
}

@xfpd

The ANSI codes are not VT100/52 etc. codes although they are close relatives.

ANSI codes were introduced to be terminal vendor independent (VT100 was not).
On the first PC's in the 80's you had to install a ANSI.sys driver to use these sequences.
