Reset Arduino (mkr1010) using USB connection

Is there a way to force a reset (using arduino-cli tools or otherwise) without uploading SW to the device? (MKR1010).

The closest I have come (googled and tested a lot) is to be able to force the device into programming mode (led pulsating), but not reset/restart

import serial
import time

com = serial.Serial(sys.argv[1], 1200)
#com.dtr=False # this line True or False makes no difference (works anyway)
#time.sleep(0.5) # not needed

(linux pc)
python3 -m virtualenv venv
source venv/bin/activate
pip3 install pyserial
sudo ./venv/bin/python "/dev/ttyACM0"
=> MKR1010 enters programming mode

Not sure what is the use case so this may not be relevant solution, but you can reset the board by a routine listening to Serial, send whatever code you want and perform a reset by calling NVIC_SystemReset();

Although it is possible to cause a reset via the DTR control signal on the serial port when using a classic Arduino board like the Uno, Mega, or Nano, it is not possible to do that with the MKR WiFi 1010. The reason is that the MKR WiFi 1010 has a native USB capability where the primary microcontroller is attached directly to the computer via the USB cable, so it doesn't have the auto-reset circuit like the boards that use a dedicated USB to serial adapter chip do.

As you already learned, the system used to put the native USB boards into bootloader mode is opening a serial connection at 1200 baud. I think that's as close as you're going to get to being able to alter the run state purely from the PC end.
