Serial.readBytes and Serial.peak
Put in probably temporary bandaids to allow code that uses:
Serial.readBytes(Buffer, cnt);
To function. It simply loops calling the underlying code for Serial.read().

Fix: write returns zero ( #202 )
https://forum.pjrc.com/threads/40893-Incorrect-return-for-Serial-write()-on-Teensy-3-6?p=127732#post127732
I'm not sure if this fix has some side-effects - how will other functions react when it does not return zero anymore ?

Report Serial bool operator true only after 25 ms
Sometimes the PC or Mac drivers are not actually ready to begin receiving data immediately after they cause DTR or RTS to assert. This delay allows the PC to become ready before we tell sketches the Serial device is true (ready).
