No Carrier error causes loop attempting redial multiple times per second.
Last modified: 2007-04-18 12:49:03 EDT
Description of problem: When wvdial is the dialler for a ppp interface in DEMAND mode, and for some reason it gets a "NO CARRIER" error, it redials immediately but allows no time for the call to go through. This looping occurs multiple times per second until the process is killed. It appears the failure condition or a timer for failure to get carrier is not getting reset when redialling. Version-Release number of selected component (if applicable): wvdial-1.53-7 How reproducible: always Steps to Reproduce: 1.Configure a ppp interface in DEMAND mode with WVDIALSECT=someconnection 2.During dialling disconnect the phone line, pause, reconnect to cause connection failure. Actual results: wvdial loops, not waiting even for echo of the dialled number before declaring NO CARRIER. Expected results: Redial attempt that allows time for call to go through and carrier to be established. Additional info: I changed to a chat script which does not have this problem. Perhaps chat should be the default?
