Hi List: Again to let all members of this list to know that I am plain newbie as far as 3Com TC is concerned. This is my first stab at it and I am at a point where I am trying to download software. I have been reading the posts on this list for the last month or so. Many of you folks have recommended to install the following software versions: 1) HiPer NMC: Version 8.6.3 I have installed it on the card without any problem. 2) HiPer ARC: I have Version 5.3.3 but some experts on this list have recommended that V 5.3.110 is more stable. Is it correct? I have not been able to find a download for V 5.3.110. Can somebody forward a URL link to me? 3) HiPer DSP: I have V 3.5.12 however some experts have recommended using V 3.5.105 or 3.5.109! Is it correct? Which version if better: 3.5.105 or 109? Again I will appreciate i9f someone can email me the URL link because I can not find it. Thanks. This is the best user group on the Internet.
