    Which serial port to choose in the Arduino IDE?


    I'm wondering which serial port to choose in the Arduino IDE [from Teensy Ports or Serial ports] and why. As far as I can tell it doesn't matter for the serial port functionality?

    Using Windows 7, Arduino 1.8.10, Teensyduino 1.49b4, Teensy 3.2 & 4.0.

    Your help is appreciated,

    Using the Teensy Ports is best for Teensy as it uses PJRC optimized code to talk to Teensy units more effectively at higher output rates, especially the T_4.0 that runs maybe 20 times faster?

    That interface is also more effective at reconnecting the Teensy and computer from 'offline' after uploads or disconnects.

    Indeed either can work - but if you run into trouble in the Teensy Ports - it is code Paul can directly edit and correct.
