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.
