Hi , I've installed node-red on my iMAC and in my MacBook.
I normally work with Arduino with the IDE on /dev/cu.usbmodem144201 and /dev/cu/usbseriall-0001 for Esp8266.
In node-red I can't find these serial ports , I've tried to use the Arduino IDE with node-red , but the result it's the same.
Should I use a USB to Serial TTL converter ?
Thanks for the attention.
