TinyTERM CScript User's Guide

1 Overview

CScript is Century Software's object-oriented, JavaScript-compatible scripting language that you can use to manipulate, customize, and automate the TinyTERM environment. Through CScript, you can provide your users with automated startup, login, logout, file transfer, and remote system access. Because CScript resembles the functionality and syntax of JavaScript, learning CScript is very easy, and you can find many JavaScript resources both in print and on the Internet.
