Hello,
I was just going through references to the use of Serial.peek (for Arduino), so copied and pasted the code into a new Arduino blank sketch.
Would not compile, came up with stray "\" errors.
Only worked when every line was re-entered, The error doesn't mean a lot to me (beginner), but unless the "\" was hidden, I couldn't see any.
Cheers
PS How irritating the verification thingy is for less than perfect eyes and the "listen" option doesn't work
