IDE port ?

Is there some way to set separate port for every separated IDE instance ?

Now, if you are running two instances of IDE and both are for separated boards, you must change the port from the menu every time you burn either board.

For example I'm building a system, where two Arduino Nanos, 'A' and 'B' are talking to each other over SoftwareSerial. When I make changes to 'A', I must change port there. Now also the monitor runs for 'A'. If I want to see monitor for 'B' I must change the settings and lose, what there is in monitor 'A'. Of course I can and must use for example minicom here, or have two separate laptops, but this does not sound very 'professional' to me. Using two PC makes the project handling and documetantion very hard.

If you run two separate instances, you can do two uploads at the same time and have two serial monitors (with different com ports) open.

The trick is not to open the second instance from within the first one. You can e.g. double click each of your ino files in your file explorer and you will have two completely separated instances where one can use comX and the other one comY.

Great many thanks !
I did not even think so low level solution.

I have to test it tonight !
