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 J.

Probably a fairly nice and effortless way if it works in the first place and portability to non-Windows is not an issue. David V. ---

[http://raa.ruby-lang.org/project/ruby-gpib/](http://raa.ruby-lang.org/project/ruby-gpib/) Have not tried these personally. We use the NI Ethernet / GPIB converter boxes here at work. Everything is just a socket call, but the transfer rates are slower than the PCI cards. Blessings, TwP ---

There is some sample code here … [http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-list/20748](http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-list/20748) The code is readable if the Japanese is not 😉 TwP
