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.
