output buffer is cleared when power has been off, or after a *RST (reset) command
has been executed.
-420 Query UNTERMINATED
The power supply was addressed to talk (i.e., 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 an APPLy command (which does not generate data) and then
attempted an ENTER statement 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 all data is lost.
