Open two Arduino IDE on one computer.

Hi All.
Is can be to work on the computer with two opened Arduino IDE and each project works with own board via differ com ports? If I doing so then one of two com ports become not accessible. This is needed for debug two boards, which exchange each other information and is needed to see debug messages on bot com port monitors. Did someone do this?
Thanks.

Open a second instance of the IDE rather than file/new from the first one.

Each instance can have a different board type and COM port or speed set.

Thank You. I try this now.

Now work both com ports right.
