it returns. This allows it to connect to the server side again, which
has been listening on IPv6 addresses exclusively for more than 2 years.

then wait for the connection to be closed by the peer.
This means that commands such as ``pppctl ... show links'' will
display the correct output again (rather than truncating it depending
on how much data arrived in the last packet).
ppp descriptor and signals the terminal thread when there's something
to read on that descriptor.
This means that the main loop doesn't have to alarm() itself into
dropping out of el_gets() frequently to check the descriptor. This
dropping out was disturbing syscons (via ioctl()s from libedit) enough
to reset the screensaver timeout every .5 of a second.

Don't read(fd, buffer, 0) and think ppp has closed the
connection when `buffer' is full, instead, flush most of
buffer to the terminal and read() for a reasonable length.
This fixes "show route" when there's more than 2k of
routing output.
Remove the timeout hack to notice that ppp has closed the connection.
Remove the ``special case'' hacks for "quit" and "bye", as pppctl
now exits immediately when the connection is closed by ppp.
Suggest a secure "set server" line for connecting ppp & pppctl.
Tidy up and correct a few man page typos.
