A Python program, running as an independent process, that provides a 'proxy like' service for experiment runtimes ( psychopy ) and devices ( keyboard, mouse, parallel port, eye tracker, ... ).
True, == setting the eyelink library to use 'dummy mode' as SRR terms it. When a a can to setConnectionState(True) is made, the core eyelink DLL is opened without making an actual connection to the eye tracker. Tracker methods can be called but no data will be received by ioHub. Can be used to test experiment logic / graphics when a physical eyelink device is not available.
False == connect to the EyeLink Host, using default IP address, or that specified in the "network_settings" parameter.
