Question : How do I connect to the Internet/APN using a Siemanns MC75 modem?

Hi there,

I have been trying to get an MC75 Sharkpod modem to connect ot the internet. I can get it to send sms', but I can't get it to connect to the internet - or APN.

I have set up an internet connection using windows, and it connects fine. I used a port sniffer(HHD Software Device Monitoring Studio 5.22) to view the AT Commands that windows sends to the modem. But, when I use those commands in hyperterminal, It tells me that there is no carrier.

I have also tried using 'AT+CGDCONT=1,"ip","internet"' with no success.

Is there a command that I am missing? If I am completely wrong, could someone please give me an example of the commands needed?

The attached commands are the commands that I am using in HyperTerminal, and they are the same ones that I got off the port sniffer.

Thanks so much for your help in advance.

Hi,

Tried that but still not managed to have any luck. I still get no carrier errors.

Windows must be doing something at it not an AT command..

I am programming on .NET 3.5 and managed to find this http://dotras.codeplex.com/

It allows the creation of a Dial up and allows dialing automatically using RAS in Windows, so I have abandoned the AT commands in favour of this.

Thanks for the help though.
