Hold it!
The PPP HOWTO does not say that if your connection drops in the first twenty
seconds that it must be the modem.

It is called "famous last words!" I have heard this "we are certain
that there is no authentication being used" time and time again from
people only to find that they accidently had cycled the power to one
of their terminal servers and you never guess what the power on
default condition was . . . .
More often than not when the connection dies in the first few seconds it is
dying in the LCP and AUTH protocols. It is because the ISP has configured
authentication and you are not providing it so the IPCP sequence times out
after thirty seconds and gives up; taking down the LCP layer and the modem
with it.

Your trace was nice. However, it was inconclusive so I can't comment on
it.
The message "Timeout sending LCP requests" means that the system is trying
to send the first protocol, LCP, to the peer. When this condition happens
it usually means that you haven't started the remote PPP software.
Please try to use minicom. You indicated that you have it. Call the ISP.
Give it the PPP account name and password. Do you see strange messages such
as "invalid password" or "login:" or "host not available"? Or, do you start
to see what looks like junk with several { characters in it and starting with
a ~ character? That junk is the PPP protocol.
If you start to see the junk than recheck that you have the proper account
and password in your script. If you are using chat, put a new expect string
such as "THIS WILL NEVER OCCUR" after the last sequence. The chat sequence
will fail because this string will never be sent, however, the chat process
will log the characters which would have been given to the pppd process as
a LCP frame.
Only after you are certain that the modem is not working should you consider
replacing the modem.
Unless, of course, you are using a V.3 (300 BPS) modem. :)
