After supplying all your  Embedded Development Tool needs for 42 years
 Computer Solutions Ltd and its web shop are now closed.



 Having reached the grand old age of 75 it is time to relax and fulfil other ambitions.

 Its been an exciting ride with you, our customers, often on the bleeding edge of technology
 and I thank you for your friendship, your trust, and your orders.

Stay well        I wish you all success in your future projects.

Chris Stephens.



     But what to do with the web site ?  It has taken >12 man years of work to create a repository of knowledge on many aspects of the art and science of embedded microprocessor development and even after closing the shop it still gets over 4,000 visitors per month.  So as a service to my customers I have decide to keep it live providing my technical insights on the products and then redirecting viewers to sites where they can purchase the items they used to buy from us. Follow the link   "Home"

       The  "Information zone"  consists of articles produced as background tutorials on subjects of interest to those designing new products.  As different CPUs have became available this has lead to new development techniques and in particular to new ways of communicating between nodes.

New drivers and protocols enhance real-time TCP-IP network stack

TCP/IP Network Stack

Now available from Computer Solutions are a range of optional drivers and protocols to enhance the RT-IP portable embedded real-time TCP-IP stack from EBSnet.

The new options provide wireless network support based on the IEEE 802.11 standard, SMB (server messaging block) allowing embedded devices to share files and printers over LANs or WANs, and SSL (secure sockets layer) which encodes data to ensue security in embedded Internet communications.

The 802.11 driven network stack allows users to migrate Ethernet based embedded network applications into the wireless environment using the same API. The driver supports Intersil's PRISM WLAN chipsets, and offers a range of configuration options including continuously aware mode, power save polling and wired equivalent privacy.

SMB (server messaging block) is the network protocol used by Microsoft Windows to share files and printers over a network, and runs on top of TCP-IP as an application level protocol. Embedding real-time SMB in a system makes it able to share resources such as a disk or printer on a network or to act as a printer or disk available to the network. It operates over any Windows PC network as well as Linux or Unix variants running Samba. The EBS RT-SMB system is designed from the bottom up for compact real-time systems, has a small footprint, and is robust and portable.

The new SSL option offers 'industrial strength' authentication and encryption for embedded communication and application devices. It is based on the established OpenSSL protocol library with a restructured code base, additional documentation, and the inclusion of both Windows and embedded test and sample code. It adds security to a TCP based communication protocol by authenticating users and encrypting sensitive data.

RT-IP, developed by EBSnet Inc. of Groton, Mass., USA, is a full TCP-IP network stack for embedded applications. It can be supplied ready configured for most of the common combinations of 32-bit CPUs and compilers. It provides all the more common protocols and many advanced ones, and allows new drivers and protocols to be implemented easily and quickly.
