When Arduino starts to upload, what do the dots and underscores mean. Does the uploading start and stop or what. Often I get a message about packet time out.

Screenshot...? code...?? error message..?? required but not supplied.
Thee is no code to post. This is a question about up[loading to a ESP32 after compiling.
I get
esptool.py v2.6
Serial port com7
connecting ............____
A fatal error occured: Failed to connect to ESP32: Timed out waiting for packet header.
I ask again. what do the dots and underlines mean? Was there no connection at all, or during the uploading process. Ofter I ge3t the dot and dash pattern and the uploads correctly.
So, I ask again wht should I see when the coed is uploading???
It's just a "working" indicator while the IDE tries to connect to the ESP UART. They have no meaning, except that you shouldn't see them because the PC connects to the UART very quickly.
Make sure you have a good USB cable, try using a different USB port on the PC. Which ESP board is it? Some NodeMcu clones require you to press a flash button.
Here is what a normal upload looks like:
Sketch uses 261888 bytes (25%) of program storage space. Maximum is 1044464 bytes.
Global variables use 26936 bytes (32%) of dynamic memory, leaving 54984 bytes for local variables. Maximum is 81920 bytes.

This is what I get
This ESP32 connects and loads but has the dots and dashes.
I have another ESP32 that connects with only a few dots. BTW, I noticed you are using the version 2.8 of the programming tool. Should I update? How would I do this?
I just upgraded to Arduino1.8.10 and it still has version 2.6 of the programmer.
I will try other USB cables and ports as I have some intermittent issue here it seems.

Steve Mann, I see that you are using esptool.py v2.8. How did you upgrade your Arduino to use version 2.8?
Mine is version 2.6 and I recently upgraded to Arduino 1.8.10
