In response to increasing demand from our customer base for software to enable connection to the Internet etc., and coincident with the launch of our range of new networking products, the Network Group at Acorn Computers have arranged to make available a release of Acorn's implementation of the TCP/IP protocol stack: this is subject to the licence conditions detailed in the documentation accompanying the software. The released software consists of two archives ('Spark File' type produced with David Pilling's !SparkFS) containing software and related documentation, both software items being compliant with the DCI 4 specification, as used in all new Acorn AUN products :- 1) the 'Internet' archive, which contains the TCP/IP protocol stack itself. 2) the 'BootNet' archive, which contains the AUN protocol stack. Both archives, with attendant ReadMe files describing licensing etc, may be found in ftp.acorn.co.uk:/pub/riscos/releases/DCI4/* This release does not include the client tools which form a part of the 'Acorn TCP/IP Protocol Suite (Release 2)' product, nor does it include some of the more advanced components of the networking software which are present in the above product. We would like to take this opportunity to thank all of our colleagues who have made this possible, especially Technical Publications, the Legal Department and senior management, and the third party developers for their permission to include the various hardware drivers that they have supplied ; last, but by no means least, special thanks to the members of the Network Software Development team. Acorn Computers Ltd. reserves the right to revise or withdraw this software release at any time, without prior notice.
