Here is a diff of /usr/src/usr.sbin/ppp against current. The diffs

add some logging functionality which I find very useful.
'set debug link' will record just link up/down and address assignments.
'set debug connect' will record the entire chat dialog
'set debug carrier' will record just chat lines including 'CARRIER'
(so that I can be sure I'm getting a 28.8 line).

There was a global change required to permit LogPrintf to take a bit
mask instead of a bit position value (to permit logging some events
on either of two flags, so that no change in 'set debug lcp' would
result from the code supporting 'link'.  Thus the diffs are rather
long for such a small change.  The man page is also touched.

Oh, and there was a slight syntax problem in route.c
