SPDR
EDR is output in the event order, separated by a delimiter.
It is output for each event sequentially, finally followed by the END event. The format for
END event is given below.
For the format for each event, refer to “EDR” since it is the same as that for EDR.
In the case of RS-232C: All the events are output at once, with each event separated by a
comma (,).
In the case of GP-IB: Created by dividing the return value for each item using the
delimiters (CR and LF), and outputting the items one after
another.
