I've been tracking this fairly closely, and to the best of my knowledge and belief, the Rockwell implementation of the proposed V.90 standard is not currently interoperable with the Lucent RABU (as in "PortMaster") implementation. It is my current understanding that Rockwell declined to participate in interoperability testing with Lucent until about a month or so ago. In any case, this may be an issue if there's an expectation that the MODEM's V.90 mode will be used for connection to a PortMaster. If connection to a PM is wanted, the K56Flex mode would undoubtedly work better. And it wouldn't surprise me in the slightest if the Rockwell V.90 implementation may need a tweak or two before it's both conformant with the actual standard (on track, as I understand it, for approval in September, 1998) and interoperability with Lucent gear. (It's certain that the Lucent code will need to be changed, as it's a beta version of ComOS that supports V.90 at all, and there remain some issues to be resolved. On the other hand, I fully expect that when Lucent releases the code (as non-beta), it will be solid.) david -- David Wolfskill UNIX System Administrator dhw@whistle.com voice: (650) 577-7158 pager: (650) 371-4621 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
