How to add support for modem to NM

[Peteris Krisjanis <pecisk gmail com>]

Hi there!

How can I help to add support for Huawei E1692 modem so it works up to
date in next Ubuntu/Fedora release? This is new one, doing connection
type changing automatically (roaming between UMTS, GPRS and friends).
This is used as prepaid mobile broadband modem, so it will become more
popular. Also I would like to know the steps what I should do to add
any other modem (if it's not supported).

I have instructions for PPP
(http://www.santinoli.com/open/e1692-howto.html), but of course I
would like to use NM.

Cheers,
Peter.
