  • INDI
    INDI is the Instrument-Neutral-Distributed-Interface control protocol. INDI has many advantages including loose coupling between hardware devices and software drivers. Clients that use the device drivers (like KStars) are completely unaware of the device capabilities. In run time, clients communicate with the device drivers and build a completely dynamical GUI based on services provided by the device. Therefore, new device drivers can be written or updated and clients can take full advantage of them without any changes on the client side. hot
