Adam,

I do not know the details of the distribution you are using, but I could
imagine that the part of the software which controls the modem is
'eating up' the responses of the AT cmds you are sending down with
chat(1). Concerning the time update, I'm using ntpdate(1)
to get the correct time from Internet.
