ESI: Easy software interfacing tools for Turbo Pascal programming of digital input-output devices

We describe some programming tools for real-time monitoring and control of digital laboratory devices. These create several interrupt-driven processes that operate in the “background” of the user’s program. An event buffer logs switch closures, thus helping the user’s program keep up with events. Other simple commands (e.g., TurnOn) take a line number and a time argument as parameters; they are automatically executed at the time specified. Applications to operant conditioning are discussed.
