PaulS:

  if (mySerial.available()>0){

Serial.println(mySerial.read());



Immediately, expect a one character response. Why?

Well, I'm waiting?

C'mon. Hurry up.

I'm not a patient type, either.

I am guessing you are referring to status registers? I need to wait until TX/RX is complete? I found a website on that subject that seems informative. I'll have to refresh myself.

Can I write the status registers directly into the IDE?
