USB-Serial Lag issues with Automatic Download esp_tool.py

[RMandR]

I'm noticed that automatic download through USB-Serial (FTDI) hardware does not work in some circumstances:

- running from guest VM
- Some MacOs system
- running on Host OS, but being called from within a larger GUI (python) program.

I've tried fiddling with the delays in esptool.py reset code without much success.

Does anyone have a more reliable mechanism to trigger automatic downloads?

Not sure if there has been further progress from there.

Verified. Markus has a solution in the post above that does work on Linux and resolves the latency issue.
