I have written this program that uses the packet driver to send and receive packets to some in house build 80188 controller boards and in general everything works just fine. However, during some tough testing of the SW, the test egineer experienced a couple of times a complete crash of the PC - blue screen of no return - when he switched off the LAN hub while the program was running and communicating. It was not very reproducible and I have certainly not been able to reproduce it on my development PC.
I doubt it is the SW itself as it would normally not crash so much that it would crash the entire PC. At least I don't recall ever seing that working with this SW for several years now. To get a blue screen it is my experience that you have to be really deep inside the PC (although it happened to Mr. Gates himself when he personally launched Windows 98 ). The test engineer was running on Windows98SE if that makes any difference and I myself am using XP pro. Any clues? Thanks, Jens.
