Er, not in this case, since the modem shouldn't grab the line until 
asked. There is no need to disable dial tone detection - it won't make 
any difference. The problem is not the dial tone, but the fact that the 
dial tone has "expired", because no dialing has taken place during the 
POTS dial period. This problem is caused by ALSA. More specifically with 
ALSA startup when KDE starts.
