[Almost] everything you need to know to get the best performance from a Lucent Win Modem is here. Agere Systems is the new name for Lucent's Modem division.
NOTE - many owners don't know what driver (also called firmware) version they are using! If you don't know - or haven't updated your driver - you may be amazed at how much better your modem is with the updated driver!
The Latest Driver is: Version 8.30 - available from Modemsite. The latest Modem-on-hold applet is 1.76, also available from Modemsite.
WARNING! V.92 modems based upon the 1646 Mars2 DSP will NOT support V.92/V.44 functionality with any driver after 8.12. (The driver will work, but you'll only get V.90.) For this reason, I suggest you do not purchase a Zoom 3025L or other "V.92" modem containing the 1646 DSP. See 16-Feb-02 V.92 News. The "new" driver offerd by Microsoft's Windows Update for XP (8.27) disables all V.92/V.44 functionality - this driver should be avoided if you want to use V.92/V.44 features.
