kintenet time out

Whe I was running SUse 9.2 there was a feature under kintenet to timout the modem connection if it has been idle more than x minutes/ I tried to do the same with 9.3 and it does not seem to work at all. I have changed the time from 120 to 10 minutes through YAST but no affect. Am I doing it wrong? Has some other people able to get it to work? -- Joseph Loo jloo@acm.org
