Feature request: Control cursor position in Serial Monitor

[toranlo]

Hi,
Currently in Serial Port (Arduino IDE 2.0.3) it is only possible to print text lines with LineFeed (“\n”) and auto scroll. It would be very useful to be able to control the position of the cursor to print continuously in the same lines (overwriting) without making scroll. For example in a measurement sketch to print the results in several lines (the same lines without scroll) like in a LCD display.
This cursor control position can be done using the well-known VT100 escape sequences. I suggest a minimal implementation and an enhance one.

1. Minimal implementation (Carriage Return and Cursor Up one line)
   It is enough for most of sketches. “\x1b” represents the Esc character.
   “\n” or “\r\n” Line feed and Carriage Return (like is currently implemented).
   “\r” Carriage Return without Linefeed
   “\x1b[A” Moves the cursor one line up

2. Enhance implementation (Full cursor control)
   The previous minimal implementation plus the following escape sequences (N represents a decimal number):
   “\x1b[NA” Moves the cursor N lines UP
   “\x1b[NB” Moves the cursor N lines DOWN
   “\x1b[NC” Moves the cursor forward by N columns
   “\x1b[ND” Moves the cursor backwards by N columns

Thank you very much

Hi @toranlo. Thanks for taking the time to submit an issue.

I see we already had prior requests for this or similar features, which were declined:

• Terminal escape code support in Serial Monitor Arduino#9102
• Proper handling of CR/LF in serial monitor [imported] Arduino#346
• Serial monitor does not honor some characters Arduino#3654

There is a different take on adding such support here: #406

It is best to have only a single issue per subject so we can consolidate all relevant discussion to one place, so I'll go ahead and close this in favor of the other.

If you end up with additional information to share, feel free to comment in the other thread.
