serial.write(byte)0)

the programmcode 👍
serial.write(0);
will work with arduino uno / mega

but with :
arduino 101
arduino MO
chipKIT uC32

I get an compiler error 👍

test_serial:31: error: call of overloaded 'write(int)' is ambiguous

Serial.write(0);
**********************************
use :Arduino 1.8.1
win 7

Start by reproducing the Serial.write(0) compiler error with Arduino 101, Arduino MO, and chipKIT uC32 using Arduino 1.8.1, then inspect the Serial.write API entry point. Done means the same call compiles consistently on the affected boards without breaking the existing Arduino Uno and Mega behavior.
