This the first release of a free TCP/IP/PPP protocol stack for the uC/OS Real-Time Operating System. As a first release it s still rather rough and very much larger than desired however it is working well in an embedded product and therefore may be useful to others. Much of the code is ported from public sources including BDS Lite and KA9Q (and its derivatives) and carries copyright notices from those sources. Essentially TCP is based on KA9Q but with ideas from BSD, IP is a simple implementation supporting BSD structures, ICMP is ported from BSD, and PPP is ported from the BSD version of the distribution common to BSD, Linux, and many other systems
