This is a common problem: Take a look at the ModemSetupAACmd for the
rockwell modems for a better solution to doing so
automatically. Certain modem manufacturers seem to have just gotten
universally setting auto-adaptive wrong, only testing with specific
software with the company's own published init strings, for example.

Friend, I think this is a wrong approach. It forces all connections
directly to your PPP srevice. Instead, why not use a "${username}ppp"
login name with /usr/etc/ppp-login as their login shell? This permits
the normal getty to handle the line, for standard log-ins if needed,
and does not force PPP access. I've used this at work with
considerable success, and so does my ISP. I dial in as raoulppp, and
run a telnet under raoul as necessary for shell access.
