One thing that can cause this is Xon/Xoff flow control 
interfering with the setup of the low level link (the LCP
process itself).  However, it looks like your serial port 
may not be init'd correctly (not 8N1) by setserial.

_Most_likely_ cause is ppp not starting at the other end:
a) you didn't tell it to in your chat script or
b) remote server is slow.

First of all pass "debug" option to pppd to see what's happening
during login -- you should be able to figure out whether a) is
true.  It also helps to login manually once (use minicom) to find
exactly what's your ISP's login sequence.

If it's b) try "silent" or "passive" option to pppd, and/or try
setting timeouts in your chat script (explained in pppd manpage).

"Link not 8-bit clean" in this case means that your pppd is talking
to command line prompt of the remote server, and it echoes everything
back.
