This appendix contains an annotated sample of an application using ADCCP,
illustrating communication between two combined stations. The example includes
most of the requests described in Section 6, “Requests and Responses.” The
annotations include comments on the code as well as cross-references to parts of this
manual where specific topics are described. Annotations are in boldface type.
