manually entered download mode, saw "waiting for download", what is next?

Yes I know, there are tons of similar posts, and I do read them through, but cannot get my problem solved
So basically I made a custom board based on ESP32 WROOM module. Then I used "make monitor" to monitor the serial port output. By toggling the GPIO0 button I am able to see ESP32 is entering download mode with the indication: "waiting for download". (Even to this stage takes me several days, but its a another story )
The question is now what is supposed to be the next step? In the command window where this waiting message is, I cannot do anything, as the input from keyboard is blocked.
I did the following tries:
1. opened a new console, did "make flash" from there, was told that COM port cannot be opened. I tried also to use esptool.py directly, same result.
2. used esp32 download GUI tool, same error message: COMx port cannot be opened.
3. used arduino IDE to upload, same error. I tried also first to move ESP32 to download mode, then started uploading, no success.
So I think the problem is the monitoring console where I run make monitor is occupying the COM port, other console or tools cannot access the same port.
What should I do now? Any hint is appreciated. Thanks.
