Note: After a command or query with or without a response, the *STB?
query responds with hexadecimal number with bits mapped as in the table
above. The *STB? query clears the command status byte as does any other
correctly completed command. The bits are "sticky" through the sending
of the *STB? query response but are cleared after the data is
transmitted.
