Appendix B: Common commands
When set, indicates the following has occurred:
All pending selected instrument operations are complete
and the instrument is ready to accept new commands.
The bit is set in response to an
command or TSP opc() (on page 8-77) function.
Not used.
Attempt to read data from an empty Output Queue.
An instrument operation did not execute properly due to
an internal condition.
The instrument detected an error while trying to execute
a command.
A command error has occurred. See information
following this table for descriptions of command errors.
The instrument transitioned from remote control to local

since the last time this register was read.
*ESE 145 sets the Status Enable register of the
Standard Event Register to binary 10010001,
which enables the PON, EXE, and OPC bits.
*ESE? might return the string *ESE 186,
showing that the ESER contains the binary value
10111010
