Greetings, Is anyone aware of a Ruby library for controlling IEEE-488 interface cards? The specific application that I am having to work with is running MS-Windows XP and uses National Instruments IEEE-488 interface cards. So far a search of this newsgroup and the general web hasn't returned anything promising. NI normally provides several levels of drivers, ranging from direct port access through DLL and COM interfaces. Use of any of these would probably be acceptable. Thanks, John --------------- Dr. John Joyce LIMS Manager Division of Consolidated Laboratory Services 600 N. 5th St. Richmond, VA 23219 Mailto: John.Joyce / dgs.virginia.gov <--- Address Change Phone: 804-648-4480, X-384 FAX: 804-692-0416
