LQM and HDLC timer diagnostics come out with the correct name.
o Don't send an LQR immediately upon reviving a datalink. Leave
it 'till the next timeout.
o Add the link name to some more LQR diagnostics.
o Break out of the main loop when a descriptor exception is seen
in select().
o Remove the evil nointr_[u]sleep() functions. Timers should be
(and are) used instead.
o Treat a read() of 0 bytes as an error that's fatal to the link
on which the read() is done. We should never read() 0 after
select() says there's something there - not unless the link
has been closed by the other side.
o Write the data seen before a HDLC header to the terminal in
`term' mode, *not* back to the modem :-/
o Initialise our transmitted file descriptor before starting any
timers.
o Only send data links that have *no* pending output data. This
means that our final ACK will be written rather than being
nuked with the datalink transmission.
This program was originally written by Toshiharu OHNO <tony-o@iij.ad.jp>,
and was submitted to FreeBSD-2.0.5 by Atsushi Murai <amurai@spec.co.jp>.
The original version was usually referred to as iij-ppp.
Ppp is currently maintained under FreeBSD and OpenBSD by Brian Somers
<brian@Awfulhak.org>. The sources for both operating systems are the
same although the Makefiles vary due to the nature of each system.
If and when it's ported to another OS, things will probably be shuffled
around so that there are several Makefiles, one per architecture.
The latest sources are available in FreeBSD-current and OpenBSD-current.
An archive hacked so that it will build on just about any version of
FreeBSD is frequently generated and made available on
http://www.FreeBSD.org/~brian. Once the first OpenBSD release is made
with ppp, an up-to-date OpenBSD archive will be made available too.
A FAQ is available at http://www.FreeBSD.org/FAQ/userppp.html. It applies
equally to OpenBSD as it does to FreeBSD. The man page is quite extensive,
and there are lots of examples in /etc/ppp/ppp.*.sample. These examples
come with the hacked archive above but must be installed manually.
Ppp is still under development. There is no official TODO list.
