I will see if I can sort out the disable-dtr-rts-properties
Sorry folks, my bad:
My initial comparison(June) was just plugging the target into a USB port OSX/Win to power it up.
OSX driver by default (no program using it) sets the RTS/DTR LOW.
Windows driver, guessing the COM port not being open, did not set the pins LOW so it could run the board.
Like OSX with espressif Alpha 2.0.0, Win IDE 1.8.13/16 will program the ESP32C3 DEV board but on reset,
if the serial monitor is open, RTS/DTR is set LOW. Toggle the board ON and OFF by closing and opening the serial monitor.
When I contacted the Eng at Nanjing Qinheng Microelectronics Co., Ltd. , he confirmed the OSX driver by default
will set the RTS/DTR LOW. Target board will not power up with CH341ser 1.5 so he sent CH34XSER_MAC_V1.1.
If no program is using the driver RTS/DTR is set HIGH and the target board will power up. Progress!
The program OSX "SerialTool" had no issues with RTS/DTR.
I could plug the board in and see serial data flowing. (Don't think had this prog before the new driver...)

Note the diagram is not correct and there are errors in the breakout pin assignments.
