Serial.on() issues...

Thanks, Gordon and allObjects.

I'll update tonight and try out bind(). That will make the code a lot more readable - can I get rid of the global reference entirely with:

function EasyVR(ser,onCm,onTo) {
  this.ser = ser;
  this.onCommand=onCm;
  this.onTimeout=onTo;
  this.ser.on('data',this.onWatch.bind(thi­s)); // <--------------
  this.vrstate=-1;
  this.stsr='o';
  this.rcvv="";
} ;
EasyVR.prototype.onWatch=function(data) {
    console.log(this);
};

I'd really like to get rid of it, since it does defeat the purpose of the class.

yeah, onData() makes a lot more sense than onWatch(). The variable naming there is very dubious overall, and needs to be cleaned up.
