Is it just me, or are parallel ports prone to failing without warning? Is this part of the reason parallel ports are now obsolete? (Fortunately, I've never had problems with USB ports.) I just had the parallel port of my 10-year-old Dell desktop die on me. A few years ago, the parallel port of my now 9-year-old IBM NetVista desktop die on me. So I guess I've now been forced out of the parallel port era. -- Jason Hsu, Linux-literate embedded engineer (952) 715-7661 embedded_engineer at jasonhsu.com http://www.jasonhsu.com/ee.html http://www.jasonhsu.com/swrwatt.html http://www.jasonhsu.com/ee-robot.html
