Add board reset button to Serial Monitor

[night-ghost]

Describe the request

Add a button to Serial Monitor that resets the connected board.

Sometimes hardware Reset button unavailable (Arduino via RDP for example) so we need the ability to reset without reflashing the board.

Arduino IDE version

d6a4b0f

Operating system

All

Operating system version

Any

Additional context

Additional requests:

• feature request: 'reset target' from serial terminal Arduino#8148
• [Feature Req] Serial Monitor with 'Send RST' button. Arduino#8529

Issue checklist

• I searched for previous requests in the issue tracker
• I verified the feature was still missing when using the latest nightly build
• My request contains all necessary details

What a simple feature. Never thought of this, but it makes totally sense. I like the idea.

[matthijskooijman]

This button should probably be called "Reconnect", though, since boards do not necessarily reset on (re)connect (most do, but not all).

[NicoHood]

Or we just add buttons for DTR and RTS. Then the user can manually pull those lines, for those who want to hold the line down. I heard that some people need this for ESP anyways. Then its even more functional.

[matthijskooijman]

That would work (See arduino/Arduino#3386), though it might be less novice-friendly perhaps.

[NicoHood]

That is totally different from what the user wants here.
We do not want to set DTR/RTS at the beginning fixed, we want to change it at runtime in the serial monitor, to actually reset the mcu.

[matthijskooijman]

@NicoHood, that issue also talks about having the pins GUI-configurable, though I now see it's not the original request. Should have read it better before linking :-)

Another user here. One workaround (at least on OS X) is to use baud pulldown menu and select same rate again, which resets the connection, and resets the board if auto-reset is enabled on it. Reopening the serial monitor is also sufficient, no need to reflash.

[chrstphrchvz]

I think the idea of the "Reconnect" button is helpful in the case where the board was unplugged, then reattached. The serial monitor doesn't automatically reconnect in that case, nor does it acknowledge that the board was unplugged, but a "Reconnect" button is a convenience over reopening the serial monitor.

great. so in nearly 3 years this has not been implemented?

I agree, the IDE has plenty of spare "square" buttons besides Verify, Upload, New, Open and Save. Also the Serial monitor can add an extra button for "Reset Target" as well.
