Then in a DOS window (in a clean directory for this purpose!) you do: gzip -d ppp-2.3.5-36.tgz tar -xf ppp-2.3.5-36.tar This will yield a new directory called ppp-2.3.5-36 which contains lots of files. I do not have this package installed but if you have grep (grep.exe) or a search utility that searches inside c and h files (I have no idea how to do this in windows). You want to search for words like: ConfReq ConfAck ... The place where they are used contains the C code you need to cut&paste to write a PPP post-moretm analyzer. You will likely need the RFCs too. Some (many) features of the NCP negotiation for special (cellular) networks are unpublished... good luck. The ppp package version 2.3.5-36 is something taken from a running machine. You might find something more recent. Peter -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
