12	12
13	13	* A Console window which use can do debug via AT Commands.
	15	+
14	14	* Test the poll command to RS485 sensors.
	17	+
15	15	* See return from RS485 sensors and preview process command for returns.
	19	+
16	16	* Generate the AT Commands after debuging.
	21	+
17	17	* Write the AT Commands to end node in batch.
