With the development of VLSI technology, more and more desktop computers are coming into the marketplace. A need is often felt to network these computers together to share their resources for a larger application where the data needs to be interchanged between these computers. This thesis work is an attempt to design and implement a communications package that allows various desk-top computers to communicate between each other by exchanging data between them. The computers in this network send data to each other through a central message server. Physical medium of communication between these systems is standard RS-232C communication lines. The message server holds the message until the system to which the message was addressed requests for this message. Attempt is made to design this package based on the seven layer ISO Communications Model. The design is flexible enough to permit easy expansion of the network layer services for packet routing, congestion and flow control, etc.
