    Teensy 4.0 USB Serial limitation to 64 characters?

    Hi,

    while writing a program for the Teensy 4.0 I ran into a hang when using USB serial. I was able to boil it down to the simple fact that when using Arduino serial and sending a line with more than 64 characters from it, the Teensy will hang. Reproducing was easy for me: Use the "Teensy -> Serial -> Echo Both" example sketch coming with TeensyDuino. Start the serial monitor in Arduino 1.8.9 (that's the one I tried), enter a line longer than 64 characters (including line end) and there is a hang. Only reset will fix it. I was using 1.48 beta 3. Anyone else seeing that problem?

    Thanks!

    FYI: Teensyduino 1.49 beta 1 fixes the issue. Thanks!
