Well, actually the manual isn't wrong.  AT&F does reset the modem but to
FACTORY DEFAULTS.  ATZ re-initializes the modem to the prior settings.  If
the factory sets the defaults to no compression, no error checking, and
software handshaking for example and minicom, which sends an init string,
sets compression to on with error checking and hardware handshaking and you
send at&f to the modem in pppd the modem will stop compression etc... because
it will return to the factory settings.  If pppd sends atz the modem is reset
to the last settings used by minicom for example.

You could try running minicom, write down the init string in the serial
configuration, then run pppd with an atz string.  If minicom's init string
makes pppd work then change the atz in your chatscript to the init string
from minicom.

I hope this wasn't too cryptic.

Have a good one.
