How to save pin number and auto-connect on startup?

[David Cuenca <dacuetu gmail com>]

Hi all,

I'm new to N-M, connecting to 3G net in Switzerland using a Huawei
K3715 USB stick and Ubuntu 10.04. After the painful configuration
process (I had to enter manually "vendor=0x12d1 product=140c" in the
configuration file) everything works wonderful -- even better that the
original software.

The only thing I miss is the option to save the pin number and
auto-connect on startup.

Is there any way I can write an script for that?

Any help will be much appreciated.

Thanks and regards,
David
