Prototype - v0.0 Summer 1993

• C was chosen for all new code for portability, availability of useful code libraries and personal preference.
• The prototype consisted of (see Fig. ):
  • Server process maintaining configuration in global memory.
  • Client applications map to the global sections, make requests to the server via mailbox communications.
  • One ``system" section describing the configuration and one section for each instrument.

• Alarms are used to halt data acquisition in hardware.
• Instrument drivers linked with server. Limited functionality - one variable set or read per request. Contain interface-specific information.
• RS-232-C via LAT or local serial ports.
• GPIB via Kinetics Systems 3388 in CAMAC.
• Textual user interface using ``curses" library.
