serial port issues
I'm pretty new to max msp and I'm trying to recreate this project. When I try to run this I get the notification "specified serial port not available". It looks functional in the arduino serial monitor and if I hit print in max msp the arduino port shows up in the console so I think I'm just missing something in my patch. Can someone help me figure out what's causing the problem?
I'm running Max 8.6.5 on a Mac with an M3 chip.

One thing to take into account is that only one application at a time can connect to a serial port. Make sure that all connections from the Arduino IDE/Monitor are closed.
To be in the safe that (and for possibly excluding that this is the culprit) , close all serial connections, then close all applications that might have connected to that port and restart Max.
Also: instead of connecting to a non existing port z to close the connection better use the close message.
replacing the messages with open and close instead of swapping the ports solved it, thank you!
