Jin, FYI, This is no formal LINMODEMS support. Rather it is a loose collection of List members with mode experience, specfically included Jacques Goldberg, who is more knowledgeable than me in several areas. Ignore my previous message to run this test you just reported. This result displays the problem ----------------------------- <464.825732> hw:0,6: new state: MODEM_IDLE <464.825890> hw:0,6: modem report result: 3 (NO CARRIER) ----------------------------- slmodemd does not seem to be perceiving the "Carrier Check = no" instruction written in wvdial.conf Some work has to be done herein. THere is nothing more you can do at the moment. MarvS On Tue, Feb 2, 2010 at 12:26 AM, Jin <jinsbin@xxxxxxxxx> wrote: >
