This enables you to use your Motorola L-series cell phone to be used as a modem via the IR port of your computer. It works fine with my L7089. Select the "Add new hardware" option in control panel, select manual install for a modem, "have disk", select the driver file and it will be installed. Activate the IR connection to the phone and follow the "new hardware found" dialogue. Then set up a new dial-up connction using "Motorola L-series" as your modem or use it for faxes. You can make data calls as by a normal phone. This is the first example of a "soft modem" driver I've seen. The connection speed is limited to 14.4k.
The phone model is tri-band digital GSM and is not available in the US.
