Someone recently mentioned their PC Elevator board hogging CPU time while idling. I think I know why, and figured I'd post a message hoping that some peripheral vendors are listening. Some vendors write simple GPIB driver software, but don't use the pbu_$wait calls for getting interrupts. They run through a loop checking over and over again for their interrupts. This takes cpu time, and is pretty silly. I've seen the same problem with National Instruments IEEE-488 cards, and Mercury Systems Array processor cards. SO, if any vendors are listening, please check your software, because you might be doing more harm than good with your products.
