EXIT STATUS
The exit status of pppd is set to indicate whether any error was
detected, or the reason for the link being terminated. The values used
are:
0 Pppd has detached, or otherwise the connection was successfully
established and terminated at the peer's request.
1 An immediately fatal error of some kind occurred, such as an
essential system call failing, or running out of virtual memory.
2 An error was detected in processing the options given, such as
two mutually exclusive options being used.
3 Pppd is not setuid-root and the invoking user is not root.
4 The kernel does not support PPP, for example, the PPP kernel
driver is not included or cannot be loaded.
5 Pppd terminated because it was sent a SIGINT, SIGTERM or SIGHUP
signal.
6 The serial port could not be locked.
7 The serial port could not be opened.
8 The connect script failed (returned a non-zero exit status).
9 The command specified as the argument to the pty option could
not be run.

where at least one network protocol (e.g. IP) was running.
11 The peer system failed (or refused) to authenticate itself.
12 The link was established successfully and terminated because it
was idle.
13 The link was established successfully and terminated because the
connect time limit was reached.
14 Callback was negotiated and an incoming call should arrive
shortly.
15 The link was terminated because the peer is not responding to
echo requests.
16 The link was terminated by the modem hanging up.

As the plane took off, the pilot turned to the co-pilot and said, “Have you ever flown solo?” Co-pilot: No. Typically I fly much higher than this.
