KTS_HOWTO:KpyM Telnet Server Beginners Guide

Some people ask me to recommend eBooks and tutors on using telnet server.
What generally a telnet server does, is to send to your client application a "structure" representing the command shell of the underlying OS. How the data gets into the structure is not important; so you do not need tutorial on telnet servers, instead you need tutorial for the shell itself. In KTS case, as it is a Windows telnet server, you need tutorial for Windows command prompt.

You can find bellow short list of Windows command prompt resources that I came across:
