Are you needing a driver for:
a: Conexant cx11252-16z
b: Lucent Technologies ENF656
See the confusion that could be caused by the weird member name you chose?
Neither Conexant nor Lucent build modems.... both are chipset making companies.
What pc brand and model did this unknown modem come installed in? Or is it a retail add-on device?
ENF656 is a Encore Electronics, Inc.
Agere (Lucent) chipset V.92 56kbps PCI modem, model number, ie: a modem built by
Encore with a Agere (Lucent) EMF656 chipset. The Agere chip-making company bought out Lucent (or maybe it's vice-versa).
You could probably download a driver from the vendor of the product, however, this driver (from Encore) should work ok:
Note: Driver only supports these os's: Windows 95/98/NT40/ME/2000/XP
Not for use in Windows Vista OS.
