Yes I do remember the days when Windows 3.11 had Winsock to provide a separate TCP stack. We used it and SLIP to dial up to our ISP back then. We had to keep a Windows 3.1 box on the modem for quite a while until we worked out how to build SLIP dialup scripts for Windows 95. Sometimes I swear I was born 10 years too late :( When I first started working at PSU our PC lab was a bunch of IBM PS/2 machines connected to Token Ring running DOS and the TCP/IP shim stuff. It was weird and a giant pain in the ass to say the least. The Unix/DEC hardware was sooooooooooo much easier to manage. :-D -brian
