Robert,
Sorry for the delay in my reply, been busy...
The X.25 Switch I am working on the first of a series of network building
blocks that a group of us are working on. We, (time for the ad :-) The
Radio Amateur Telecommunications Society, are working to build a modern
network for Amateur Packet Radio. We will be working on the following projects:
1) X.25 Switch (W2VY)
2) X.28 PAD
3) X.25 interface for the BBS' we use
We have received the ISODE.3 package and will investigating it shortly to
see what we might be able to use from it.
We will be filling out the upper layers, and since I've been focusing on
level 3, I haven't been too involved with the efforts. I have been interested
in the layer interfacing and we will have documentation describing it.
The one draw back at this point is that it is based on the modified version
of X.25 Level 2, it has longer addresses and slightly different procedures
to allow better performance on a multi-drop line. We use it over radio
channels where we can not hear all other stations, because of this we are
seriously considering a Level 1 access protocol to reduce contention.
The Source and executable will be sent out in Jan '88 and posted *everywhere*
If you would like more information as it comes out please send a note to us at:

I am presently running the code in a test environment exercising the L2/L3
interactions, I hope to have an Alpha test ROM in two weeks.
When I have the test environment working to my satisfaction I will be sending
to anyone who wants to check it out, as long as they report any protocol
violations/bugs they find!!
There is a Level 3 only test environment on compuserve already, more will
follow.
Thanks for the interest.
and to think it's my first sizable C program...
only 28K in a Z80!?
