Serial port disappears with El Capitan

    Oct 16 2015 | 10:38 pm
    Hi all, Anyone else experiencing flaky serial port issues after installing El Capitan? I use [serial] to grab sensor data from an Arduino. Sending "print" to [serial] usually generates a list of ports like "Bluetooth-Incoming-Port", "Bluetooth-Modem" and "usbserial-XXXXxxXX". Now at times all I see is "Bluetooth-Incoming-Port"; the others are gone. I suspect this is a driver problem and not directly Max-related. Thoughts? Thanks, Holland
