This will + * enable Windows to use its inbuilt RNDIS drivers, negating the + * need for special Windows drivers for the device. To install, + * right-click the .INF file and choose the Install option. If + * Windows 2000 is used, the Microsoft INF file in the hotfix + * will need to be altered to use the VID/PID of the demo and + * then chosen instead of the LUFA RNDIS INF file when prompted. + * + * When enumerated, this demo will install as a new network + * adapter which ethernet packets can be sent to and received + * from. Running on top of the adapter is a very simple TCP/IP + * stack with a HTTP webserver and TELNET host which can be + * accessed through a web browser at IP address 10.0.0.2:80 or + * through a TELNET client at 10.0.0.2:25. This device also supports + * ping echos via the ICMP protocol. + * + * \note The TCP/IP stack in this demo has a number of limitations + * and should serve as an example only - it is not fully featured nor + * compliant to the TCP/IP specification. For complete projects, it is + * recommended that it be replaced with an external open source TCP/IP + * stack that is feature complete, such as the uIP stack. + * + * \section SSec_Description Project Description: + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + *
