-410 Query INTERRUPTED
A command was received which sends data to the output buffer, but the
output buffer contained data from a previous command (the previous
data is not overwritten). The output buffer is cleared when power has
been off, or after *RST (reset) command has been executed.
-420 Query UNTERMINATED
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.
-430 Query DEADLOCKED
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.
-440 Query UNTERMINATED after indefinite response
The *IDN? command must be the last query command within a
command string.
