This chapter describes the RL-TCPnet component of the RL-ARM Library. RL-TCPnet is an implementation of the TCP/IP protocol stack. The stack aims at reducing the memory usage and the code size. This makes it suitable for devices with limited resources, such as embedded systems. The RL-TCPnet library is a ground-up implementation of software routines for the ARM7, ARM9, Cortex-M1 and Cortex-M3 architectures.

User applications are written using standard C constructs and compiled with the ARM Compiler.

This chapter contains the following sections:

TCP Socket
Describes the TCP Socket, the connection modes, and the sending and receiving of data.
UDP Socket
Describes the UDP Socket, the connection modes, and the sending and receiving of data.
Configuring RL-TCPnet
Describes the configuration options of RL-TCPnet.
Using RL-TCPnet
Describes the usage possibilities of RL-TCPnet.
Describes the example programs built with RL-TCPnet.
Device Drivers
Describes how to built drivers with RL-TCPnet for network devices.
Using Serial Link
Describes how to use a serial link, a serial cable, or a modem connection to establish a PPP or SLIP link with a Windows host.
Describes the debug version of RL-TCPnet for testing the application.
Function Overview
Lists the RL-TCPnet routines.
