Browser-based Terminal for access to VistA Roll & Scroll applications

This repository includes:

• a back-end Node.js module that provides a Web Sockets interface to VistA
• a JavaScript VT-100 Terminal emulation that will run in most browsers. This is based on [Christopher Jeffrey's term.js emulator] (https://github.com/chjj/term.js/), with modifications added to provide Internet Explorer support.

Installing the Node.js module

   npm install ewdvistaterm

Installing the JavaScript terminal emulator

Copy the two files from the /terminal folder within the ewdvistaterm node_modules directory and put them in a directory under your EWD.js web server root path, eg:

   ~/node/www/VistATerm

   

Running the Node.js module

In the /examples directory of this repository, you'll find a documented example startup file: VistATerm.js.
Copy this file to the parent directory of your node_modules directory. Edit it appropriately. Then run it, eg:

   cd ~/node
   node VistATerm

Starting the Terminal Emulator in the browser:

   http://mydomain.com:port/VistATerm/term.html

Note: specify the appropriate domain name/IP address and port as configured in startup file (VistATerm.js)
