That message means that device is being used by another process.

I realize minicom is open source. As such it's not a native Apple process; it's something you installed, so you have to research how to use it. I suggest Minicom - Community Help Wiki but only because I happen to use Ubuntu Linux. Other resources are available.

If you need a serial port consider using an app dedicated for that purpose.
