take care of business. Dialing and connecting works fine and the debug output looks ok. However, when the session is disconnected the debug output goes south. It will start to flood the console with the exact same messages as seen above during a connect. In this case we may actually use the modem but need a small tweak.

My temporary fix for the problem in this case is to restart the slmodemd service right after disconnecting a session. I configure my dial­up client, Kppp, to execute /etc/init.d/slmodemd restart upon disconnect. Unarguable this is a really dirty fix, but works quite well.

15.2.3 System hang

The issue reported above together with the fact that slmodemd runs with real­ time priority by default may be devastating. When the modem daemon goes insane it will hug your CPU and squeeze it all real hard.

If the daemon has real­time priority you will have a hard to get control over you system again and a forced shutdown might be the only way out.

Note: You should always run slmodemd with the ­­nortpriority option set. Failing to do so might hang your entire system.
