It's the first place I'd look if I couldn't get access to the manual - it just needs to be adjusted to suit the dialer. It was probably not meant for pon scripting - ppp dialer like wvdial and kppp use a (slightly) different form. Treat the following with caution as I can't verify this:- I "believe" the reasoning behind supplying the APN every connection is that some ISPs have different APNs for mobile, fixed line, and prepaid accounts. (Telstra for instance, has half a dozen) So a user might use the same modem to connect using different accounts to the same ISP - just picking the best rate plan for the particular area. > > It's a PAYG dongle, if that makes any difference. It often does. If I knew your ISP I could be more specific. eg. Vodaphone in the UK uses one APN for prepaid and another for post-paid. > I expect a first-time > connection have taken place with the chatscript as it stands now as the > SIM would have been recognised. > > You can test that by using the single line CLI connection commands I've posted above - just modify the connection port and speed to suit your requirements. If it connects then you'll have "proven" that the APN is supplied by the modem. I don't know the *nix equivalent, but on Windoof I've used a USB bus sniffer to see the communication between the modem and the OS - so I know the APN is retained on the device. I don't know if it (sic) is stored on the SIM or on the modem it self. If I sound unsure of myself it's because I am. Each case is different - even from the same manufacturer. Additionally modems are often customized for particular ISPs (eg. ZTE MF-627 with hidden ports for 3Mobile). Additionally there isn't a standard in the AT commands used - though many of them originate from the Rockwell chipset. Christian's modem from Bell for instance is about 80% standard AT commands and 20% proprietary. Proprietary (in this case) == closed. But I digress, and I note that Christian has already spent 6 months trying to connect with his modem, so I'll try not to add more non-essential information to his reading list.
