Comments • The *RST default value for logical_addr is that no logical address is
selected (i.e., -1). All other commands which require a logical address to
be selected will respond with Error -221 ("settings conflict") if no logical
address is selected.
• When a command encounters an Error -240 ("Hardware Error") the
equivalent of a *RST is executed. This will cause the selected logical
address to be set to -1.
