Project Characterization Implementing a Modem driver for Windows CE by Eli Bendersky and Igor Oks Supervisor: Evgeny Rivkin

Project Purpose Modem Device Driver for WindowsCE: Gateway between the modem and applications using it.

Windows CE Overview Portable Portable Modular and Compact Modular and Compact Win32 Compatible Win32 Compatible Supports RAD Tools Supports RAD Tools Connectivity Connectivity

Device Driver Overview Driver is a program that controls a device. Driver is a program that controls a device. Each device has its own set of specific commands. Applications access devices using generic commands. Each device has its own set of specific commands. Applications access devices using generic commands. Driver accepts generic commands from applications and OS, and translates them to commands for the device. Driver accepts generic commands from applications and OS, and translates them to commands for the device.

Device Drivers for Windows CE Device Types: Built-in Built-in Installable Installable Driver Types: Native Native Stream Interface Stream Interface USB USB NDIS NDIS
