USB Serial issue with minicom 2.7.1?

A few days ago, I bought some usb to serial modules (FT232) and tried to use with my MacBook to control a hardware via console. I downloaded and installed the latest driver provided by FTDI (version 2.4.2) and also installed minicom 2.7.1 from homebrew.

Unfortunately, when I connect Macbook to the board, it hasn't any responses and my terminal window is blank. But, it still works if I connect to another PC.

I just updated to macOS Catalina and haven't tried it with previous MacOS version.

Has anyone had the same problem?
