When the DTREnable property is set to True, the Data Terminal Ready line is set to high (on) when the port is opened, and low (off) when the port is closed. When DTREnable is set to False, the Data Terminal Ready always remains low.
In most cases, setting the Data Terminal Ready line to low hangs up the telephone.
