Input Message Terminators
Program messages sent to a SCPI instrument must terminate with a <newline>
character. The IEEE-488 EOI (end or identify) signal is interpreted as a <newline>
character and may also be used to terminate a message in place of the <newline>
character. A <carriage return> followed by a <newline> is also accepted. Many
programming languages allow you to specify a message terminator character or
EOI state to be automatically sent with each bus transaction. Message
termination will always set the current path back to the root-level.
