I checked on the modem in my 7410GX, and it appears to have the same Conexant SoftK56 Data Fax Modem. I checked online, and the preinstalled driver (v7.03) is complerely v.92 standards compliant. So I ran the general AT command AT+MS=? and it returned "+MS: (B103,B212,V21,V22,V22B,V23C,V32,V32B,V34,V90,V92
),(0,1),(75-33600),(75-33600),(75-56000),(75-56000)" showing that v.92 is definitely supported. So, when the modem was listed by Gateway as 56 K ITU V.92 ready Fax/modem, they were correct. Any support person who informed you that a v.92 compliant modem is not installed, or stated that it was incorrectly listed, obviously did not know what they were talking about.
This brings us to what your actual concern may, or may not have been. It appears as though you may have been looking for the applet to control the v.92 Modem on Hold feature. Bad news is... The applet is not included with the Conexant driver and requires either a separate software installation (which Gateway does not appear to supply), or an initialization string added to the modem connection. The software applet for Conexant is NetWaiting, and you can download it here: http://support.dell.com/support/down...&fileid=108371
(Dunno if it works or not, I don't have use for it, but I did go ahead and installed it, and got it to run, so it appears as though it might work) Hope this helps.
