Hi Ulrich Thanks for your time and thanks for EZGPIB!
I rebuild and resell lab instruments. My customers are doing great work finding cures for diseases. The software to control their instruments cost between 5-40K and is hyped up garbage that eats up their meager budgets. I desperately, desperately want to write an open source replacement. I am planning on offering the "base package" for free but charging a small fee for some of the various add on instrument control modules. I also want the application to have the on-board tools required to sniff ports for the do-it-your-self reverse engineering of closed source communication. I need to sniff the communication between the instruments and their native software. Abdul, helpful as always, has shown me that I must use a card that supports promiscuous mode. I have an INES PCI GPIB card on hand and I am going to give that a try. Does anyone have experience with any promiscuous mode devices? Under Linux would be even better, if possible? Is NI spy a full sniffer? NI have been really mistreating me of late and I would prefer not to buy from them as they no longer provide free technical support(now it's $300) Thanks-patrick Ulrich Bangert wrote: > Patrick, > > as a sniffer would typically be used to locate gpib communication > problems, is there any special problem to be solved? > > >>> Is there a way to set it up to read one address continuously? >>> > > This one does not sound like a problem!?
