In Chap. 6 we introduced the basic concepts of CGI input. All eight classes of input device were described along with the concepts of triggers, measures, echos, prompts, etc. The control of synchronous modes of operation-REQUEST and SAMPLE-was discussed. These modes are synchronous not only at the interface, which is a level at which all CGI functions are synchronous, but also from the perception of the operator of an interactive system using them.
