Documentation: all there is is what comes in ppp-1.3.tar.Z, obtainable from
dcssoft.anu.edu.au:/pub/paulus, if nowhere else.
Some hints: you need to have a pppd running at both ends of the serial line.
If you set up dp-2.3, I expect it will sit there waiting for either (a) an
attempt to send a packet from the Sun, or (b) a connection request from the
remote pppd. To start it up as in (a), do something like
pppd <device> <speed> <options>
where <device> is your serial line to the Sun, <speed> is the speed you want
it to run at, and <options> can include the following if desired:
mru 296 limit packets to 296 bytes - I recommend this
asyncmap a0000 avoid sending ^S and ^Q on the serial line
In case (a) you need to add the `passive' option so pppd will just hang
around waiting for the other end to initiate a connection. In either case,
the pppd on FreeBSD will exit after one ppp connection is initiated and
terminated, so if dp times out and disconnects, you'll have to run pppd
on the NetBSD end again.
There have been some recent changes to if_ppp.c and pppd - they are included
below, check your sources against them.
