Query UNTERMINATED
420
The power meter was addressed to talk (that is, to send data over the interface) but a command has not
been received which sends data to the output buffer. For example you may have executed a CONFigure
command (which does not generate data) and then attempted to read data from the remote interface.

Query DEADLOCKED
430
A command was received which generates too much data to fit in the output buffer and the input buffer is
also full. Command execution continues but data is lost.
