I have the same problem, but on debian testing (lenny). After update, new version of sl-modem-daemon came in, and modem stopped working, same error ('NO CARRIER' immediately after starting of dialing).
So, I downgraded package to previous version, sl-modem-daemon_2.9.9d+e-pre2-10_i386.deb to sl-modem-daemon_2.9.9d+e-pre2-7etch2_i386.deb, and everything works fine, like before (you can download old sl-modem-daemon package from packages.debian.org, section etch, and install it with 'dpkg -i old_package_name.deb', that is all to do for downgrade). Thank you very much, Adrianus.
