What I heard from Federico, the manager if Red Hat Milan, the default dial command (ATDT) doesn't work everywhere in Italy. Replacing ATDT by ATX3DT will work everywhere in Italy, and anywhere else in the world as well. It might be worth changing this (at least for the Italian version). Jules
The X3 disables checking for a dial tone before dialing, which is undesirable.
Yes. In Italy, the default dial-tone is not recognized, so they have to use this feature. It would be nice to document this somewhere, or add a feature to disable dial-tone checking. I mean: nice from a user-perspective, not from a programmer's perspective ;-)
This must just be for some modems though, right? Or are there no modems that can recognise an Italian dial-tone? (!)
I'm not sure. Contact federico for more details.
I wonder if putting 'AT+NCnn' would help for the internationalized distributions. So for example, AT+NC8 for Italy.
The +NC command appears to be non-standard -- if it isn't supported by all modems, it 's not going to help.
FWIW, ATX3 must be used in Finland very,very often too.
this can be configured in redhat/system-config-network as an init string
