eRTOS is no longer officially supported (2006)

You are still free to use it, and I continue to sell manuals and answer general questions about it. I just decided to stop adding functionality to it or fix earlier design decision. The system is quite stable, the only weak part is the RS-232 serial handling code.

Background

eRTOS was written by Erick Engelke. His WATTCP TCP implementation, completed in 1989, was distributed freely and has been upgraded and verified against all other major TCP implementations in the years since the initial release. This cross-testing is imperative to verify compatibility with other vendor's products

Due to his experience in both networking and embedded systems, Erick was frequently hired as a consultant for commercial and embedded applications. During those years he wrote eRTOS to simplify his own embedded systems and to improve the delivery times.

The result is an environment where one can often have a working application in hours rather than weeks thanks to the powerful building block approach. Significant cost savings can be realized since eRTOS includes extensive libraries to save the developer from writing much from scratch - as is all too common.

While his famous WATTCP is included in this system, about 70% of the code has only been available commercially, and at a significant price.

JK Microsystems is the industry leader in embedded DOS controllers. It has chosen eRTOS as an ideal way for its customers to quickly develop applications on its controllers.

eRTOS combines the most frequently requested embedded features (threads, messages, serial i/o, etc.) with Internetworking smarts in just a few lines of code.   It is the ideal way to write an embedded application for today's Intel-compatible embedded systems.
