Update: By lifting the handset I can hear the number being dialled, and the usual response. It is in the middle of that response that I get the NO CARRIER error message. Apparently, upon encountering that the modem does NOT hang up, but tries to dial again, causing the NO DIALTONE error. But still, why am I receiving the NO CARRIER error? 2011/1/24 Jacques Goldberg <Jacques.Goldberg@xxxxxxx>: > First of all thank you very much for correcting $HOME/.wvdial.conf > missing the leading dot before wv > > > I am not sure it is a good idea for me to creep into your case which is > already complicated.
