Hi all, I've got a bunch of Quad modem cards in a TC1000 chassis and was just wondering if there is anybody reading that might have any additional information on the S67 and S68 registers on these. I've searched the archives and the web for info on bits S68.1 and S68.2 that seem to be related to data over voice (DOVBS), but can't find anything else about it. While I can see from the docs that: S67 - Bit-mapped register Controls V.110 connections. Bit Function 0 Enable V.110 fallback while originating or answering, when Modem is set to auto detect. 1 Use a fixed network rate. 2 Fix the network rate at (1:64 Kbps; 0: 56 Kbps). 3 Reserved 4 Reserved 5 Reserved 6 Reserved 7 Reserved S68 - Bit-mapped register. Controls digital connections. Bit Function 0 Prevent analog calls over digital data connections. 1 Reserved 2 Reserved 3 Reserved 4 Disable asynchronous/synchronous PPP. 5 Disable X.75. 6 Disable V.120. 7 Reserved Some of those "reserved" bits seem to be no longer reserved, at least according to the release notes. Any help would be greatly appreciated. Thanks, Todd Williams Network Admin
