configuring mobile broadband at startup

[Michael]

Hi,

I'm using cdce interface to get online. But before I can get IP address 
on my ue0 interface with dhclient, I need to power up and configure the 
GSM modem.

At the moment I'm doing it by hand with cu(1) utility. How can I get it 
automated so that ue0 is running right after system startup?

I know I can make a custom shell script but is there a proper way of 
doing it? Does the system provides some configuration mechanism at 
system startup time?
