> Post a trace from the online decoder, and we should be able to help you.

I've made a mistake in describing what I'm doing, it seems. Although I'm
playing with Rifidi because it seems generally better and isn't linked to
any specific vendor, the only client examples I have are vendor specific,
and they'll only talk to their own readers and reader simulators. On port
1005. The clients do autodiscovery and won't let me talk to Rifidi.

So I do have a 52K PCAP file that I can mail if anyone wants to have a
look but the ports are wrong for the online decoder, and it seems pretty
clear that there's funny vendor specific stuff going on- manual decoding
is error prone, but the initial packet sent from client to reader is only
114 bytes and I've taken a fair length of time decoding and checking it,
especially around the stuff that doesn't make sense. I was worried that my
understanding was way off, so it's reassuring having other people say it
seems odd.

The problem is that my boss isn't happy to have open source stuff because
of the issues of copyright breach on the one hand and the perceived
requirement to open source anything that in any way uses open source
stuff. I went down the route a couple of years back to use a lovely
library of little utility routines and even had email assurances from one
of the lead contributors that the license it was under (LGPL) allowed us
to call the libraries without opening our code. Didn't help, so I have to
periodically reinvent the wheel.

Since there's substantial cost to re-inventing the wheel, I'll make
another attempt. If I joined the dotnet effort what would be the
implication? I assume the toolkit will be done as a seperate DLL or
assembly that can be called by our closed code?
