Section 6 Talker Output Format

6.2 Response Message Functional Elements
Response messages output from a talker are terminated with an NL^END signal, allowing the controller to accept
them. Functional elements of these response messages are explained here.
Rules for syntactical chart notation are the same as those for program messages, so see section 5. Functional and
coding elements which are the same as those of program messages are not explained in this section, so see section 5
for them.
