So I’ve been using Putty to talk with Arduino Micro and I have only 4 Commands or actually Char X, S, C & R
R is a resume command and the X is the exit command, I echo the Serial.read to the terminal because I had automatic resumes that seem to occur without reason
The code which works resumes ckSerialIn() if it receives a char it does not understand, so it’s doing what it’s suppose to. However, I noticed on the output of the terminal when I physically send X to stop everything and don’t touch my keyboard or mouse the loop resumes again and the chars I get are

Is there some significance to this [28~???
