+** ChibiOS/RT port for x86 into a Win32 process **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs under Linux as an application program. The serial I/O is
+simulated over TCP/IP sockets.
+
+** The Demo **
+
+The demo listens on the two serial ports, when a connection is detected a
+thread is started that serves a small command shell.
+The demo shows how create/terminate threads at runtime, how listen to events,
+how ho work with serial ports, how use the messages.
+You can develop your ChibiOS/RT application using this demo as a simulator
+then you can recompile it for a different architecture.
+See demo.c for details.
+
+** Build Procedure **
+
+Makefile.
+
+** Connect to the demo **
+
+In order to connect to the demo a telnet client is required. A good choice
+is PuTTY:
+
+http://www.putty.org/
+
+Host Name: 127.0.0.1
+Port: 29001 and/or 29002
+Connection Type: Raw
