I have a synchronous adapter that supports X.25 and Synchronous PPP on
Windows. I can dump the frames to a text file but would really like to

1) dump them in some common format (e.g. libpcap?) so that they can then
subsequently be read and decoded by ethereal (off-line)

2) write a capture driver (presumably NDIS LAN)which can pass up copies of
the frames in real-time thereby allowing ethereal to process them
dynamically

I'm sure that this is quite straightforward (I've produce a fair few NDIS
drivers before) but it would really help to have

1a) a sample X.25 and/or Sync PPP dump in libpcap format for me to study
1b) a definition of the file format together with details of the constants
required to identify the frame (link and packet) types

2a) details of the header (pseudo-MAC?) that should be stuck on the front of
the raw frames before the capture driver passes the packets up the stack

Any help would be much appreciated? 

Thanks

Will
