SCPI Command Terminators
A command string sent to the instrument must terminate with a <new line>
(<NL>) character. The IEEE-488 EOI (End-Or-Identify) message is interpreted
as a <NL> character and can be used to terminate a command string in place
of a <NL> character. A <carriage return> followed by a <NL> is also accepted.
Command string termination will always reset the current SCPI command path
to the root level.
For every SCPI message that includes a query and is sent to the
instrument, the instrument terminates the returned response with
a <NL> or line-feed character (EOI). For example, if R? is sent, the
response is terminated with a <NL> after the block of data that is
returned. If a SCPI message includes multiple queries separated by
semicolons (for example "ROUTe:TERMinals?;R?"), the returned
response is again terminated by a <NL> after the response to the
last query. In either case, the program must read this <NL> in the
response before another command is sent to the instrument, or an
error will occur.
