Interface to an EyeLink-II eye-tracker.
This requires the EyeLink development kit for Linux, available only from SR-Research to select registered users. NOTE: If you encounter an error message like "Cannot open connection, check TCP/IP settings", this may be due to the way the eyelink library figures out your host's IP address, which is through resolving your hostname (nasty!). Since typically you will have two ethernet cards in your box, one connected to the EyeLink tracker (100.1.1.1) via a crossover cable, you need your hostname to be associated with your IP on that network (e.g., your IP will typically be 100.1.1.2). Check your /etc/nsswich.conf and /etc/hosts to make sure this is the case.

Since there is no quick calibration for ISCAN, this is like a full calibration.
