Using 2 ESP32 simultainly in CPU

[wgps2024]

Hello. I bought 3 ESP32 this week and I need to connect them. The first one will send data to another one through UART2 pins. All my COM ports are working good but when I connect both in my computer occurs an error. The first is COM5 and the second COM7.
I am using VSCode + PyMakr + MicroPython and DOIT ESP32 DEVKIT V1.
The question is: Can I use 2 ESPs in the same computer? And can I watch the both sending and receiving data simultainly in my computer? If its works, how can I fix my errors? Its necessary to download some software?

Thank you.

Not a lot of detail to work with. What is the error message? What software are you using to communicate with the serial ports?
