The RUN button will reboot the attached device. Depending on the speed of the device, the speed of the connected computer, the USB tree and the contents of the boot scripts, this make take some time. Instead od just sending the script to run after some time, we now first wait for the python prompt to appear. This brings a robust RUN behavior.

I ran a classroom using Mu and many ESP devices. In the classroom were about 40 students with different laptops. Running code was troublesome. The behavior when using the RUN button was flaky, and dependent on the precise laptop. Hitting RUN and RUN again gave different results.
What happens is the following:
Inspired by the mpremote tool I implemented a handshake on the serial port for the RUN command.
This works fine in my environment; it provides a robust solution. Please note, the testing has been limited.
Glancing through the issues mentioned here at Github, the following issues appear to be similar and may be affected (solved?): #2397, #2319, #1996 and #1433. Unfortunately, I have no means to verify the last claim.
