Not a lot, apparently. I cut it out and there was still a connection.
Oh тИТ I was hoping you knew the proprietary AT commands used by this
particular modem.
The form is correct for INIT2. The OK line is not used in ppp.
(it's a response from the modem)
eg. INIT2 would be just:тИТ
So I got rid of this too. And the username/password lines. Without the
ABORT lines the chatscript is down to

OK "ATDT*99#"
You *can* connect with just a single CLI instruction... eg.
# pppd ttyUSB0 460800 nodetach defaultroute noipdefault noauth lock
usepeerdns connect 'chat "" "at" "" "at" "OK" "at&f" "OK" "atz" "OK"
"atdt*99***1#" CONNECT'
But it's not a useful form for testing purposes....
So much for searching out the files on the dongle aimed at Apple Mac
users and taking note of advice given to Windows users of the same ISP,
all of which referred to an APN and username/password!
It's the first place I'd look if I couldn't get access to the manual тИТ
it just needs to be adjusted to suit the dialer.
It was probably not meant for pon scripting тИТ ppp dialer like wvdial and
kppp use a (slightly) different form.
Treat the following with caution as I can't verify this:тИТ
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 тИТ
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 postтИТpaid.
I expect a firstтИТtime
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 тИТ just modify the connection port and speed to suit your

sniffer to see the communication between the modem and the OS тИТ 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 тИТ
even from the same manufacturer. Additionally modems are often
customized for particular ISPs (eg. ZTE MFтИТ627 with hidden ports for
3Mobile). Additionally there isn't a standard in the AT commands used тИТ
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
nonтИТessential information to his reading list.
We all pay for life with death, so everything in between should be free.
