This is the Win2000 Driver for the (In)famous Ambient (AKA Intel) 56K V90/V92 Modem with the Ambient Chipset MD3200 A. In my experience this modem performs poorly and will never attain true V90 or V92 connections. However I have hacked this driver and you will attain 115,200 bps connections virtually every time but DO NOT expect wonders from this less that desirable modem!
This is the driver (After hacking by me) found on the Installation CD included with the modem. It will give you the best performance you can get from an inferior product!
Good luck and buy a better modem next time!
