        The CLASSNET CardRoom                   provides instructors with a                   lower-cost yet fully functional                   alternative to the original                   CLASSNET control system.                   With CLASSNET CardRoom,                   teachers can take over keyboard                   or mouse functions of any                   student station to demonstrate a                   particular concept. They also can                   transfer screens to other                   individuals or groups to share                   exemplary work, or darken any                   number of screens to get the                   class' attention.                   The interface card can be inserted                   into an available slot in the                   teacher's or student's computer,                   eliminating the need for an                   external device. Functions can be                   performed from a hardware control                   panel or from Windows- based                   software; this suits classrooms or                   labs with limited worksurface                   space.                   By scanning monitors at                   sequential intervals from 5 to 99                   seconds, the instructor may                   observe student progress,                   intervening if a problem is                   detected.
