It appears that MS now *only* implements STAC option 4 under Windows 2000. Presumably, this is not supported by certain older kit that you may wish to connect with. There is a demonstratable difference between the number of ROMPs I can connect to with compression using NT verses 2000 on my dual boot system. I get compression on MORE using NT4. Since when did MS *not* remove useful features (or do anything else for that matter) for no good reason??? You are having a laugh, aren't you?? > Windows 9x/ME has STAC compression, but that's a completely different > code base. Despite the name, Windows 2000 is NT 5 - I can't think that > there's very much code in it that's been stolen from Windows 9x. I agree. However, I wouldn't be surprised if 2000's code was based on RRAS not RAS from NT4. Anyone with any sense has been using that code for years... as a RAS replacement under NT. There are very major differences (although I couldn't swear about any in this specific area) between the two products. But that could in part explain what I have noted above (I use RAS at home, RRAS at work. I have no need for the routing stuff with only one computer at home). > >However, 2000 can negotiate compression with the kit at certain ROMPs. > >I successfully use the Blue ROMP with compression under 2000.
