However, it supports the original Packet Driver spec. This has a pretty well defined interface, and all the drivers run in 16 bit real mode. There are source drivers available for almost every original card, most as antiquated as the systems ELKS is running on... : KA9Q net was the earlier package, it ran on CP/M once so may fit The KA9Q package is modular, and many items can be dropped initially, in order to make it fit. Perhaps even just IP and ICMP on top of SLIP first, and try to get ELKS to respond to a ping! ;-) Greg

KA9Q
: while trying to get KA9Q NOS to run under elks (*) i stumbled accross the KA9Q NOS... Now there's a neat little [>64k..., sorry] package that might be useable as a user-mode ELKS implmentation of IP, UDP and TCP. And it supports alot of different cards as well as serial. Let me know if you need some help. Regards, Greg

Though as Alan pointed out, the license is pretty restrictive (I > had always thought it was without any restriction at all :). I didn't think it had any restrictions either... there are hundreds of different versions so it seems... I looked at it when starting a stack for the Psion 3c, but decided it'd be easier to use the model in Doug Comer's books (since they're well documented, and there are no restrictions (as far as I could tell)) - there seemed to be a lot of stuff in KA9Q that dealt with making MS-DOS into something it wasn't. Stripping this out and porting it seemed like more work than porting Comer's... The 90%-finished fruits of my efforts can be found at http://www.gumbley.demon.co.uk/psistack.html If any TCP experts can get hold of the Psion C SDK and have some spare time, they're very welcome to help me finish the TCP layer! -- Matt J.

Argh, now you've got me rather worried Haven't got my copy here at hand, but I've read a book review (http://www.anatomy.usyd.edu.au/danny/book-reviews/h/Internetworking_with_TCP_IP_2.html) that says: "...using it does have a couple of advantages. One is that it is possible to print (and make available for ftp) the complete source code without copyright problems..." The book's software is downloadable from: http://www.cs.purdue.edu/homes/dec/netbooks.html That page even says that the book is "Ideal for implementors". I'll have to check the book's actual text to see if there's anything legal I should take care of... the last thing I want is Prof. Comer's lawyers on my back. God/ bless the Free Software Foundation... -- Matt J. Gumbley, Software Engineer | Enigma Data Systems Ltd.
