The only reported bug so far involved V.90 code that 3Com posted to its Web site this month to upgrade Megahertz Laptop modems. 3Com took down the code after the report, and was investigating to determine the cause. The problem occurred in less than one half of 1 percent of recorded downloads, according to Thea Hayden, 3Com spokeswoman, who added that 3Com modem cards carry a lifetime warranty. CityLinq system administrator Shawn Terbaville says that his customers are reporting that their initial connection rates are the same or a notch lower than when they were using x2, yet the connection appears to give them better performance in their online game playing and file transfers. NWiNET system administrator Terry Kennedy says he too is unaware of any significant performance difference between x2 code and V.90 code.
Performance is secondary to problems . . .
We didn't even tout it for the first couple of days, because people tend to blame problems on change . . . We just snuck it it. As with any code, refinements will be implemented based on experience. Because of the limitations of analog modems and telephone lines, it's doubtful that download speeds will improve much. That capability would matter, for example, when sending large e-mail attachments.
