Description

The SMU is to stream voltmeter data at a specified frequency. This requires following features to be implemented.

1) Dynamically change baudrate to suit data stream.

	-- CHANGE_BAUD

2) Start recording

	-- START_REC : Starts recording of timed data into internal buffer.

3) Transfer recorded data chunks to computer

	-- REC_SIZE : Queries number of available data points in buffer

	-- REC_DATA : Transfers requested number of data points to driver.

5) Stop recording

	-- STOP_REC : Stops recording gracefully.

6. Keep Alive Packets

   -- KEEP_ALIVE : Stops recording if keep alive packets are not received, i.e. driver is dead.
