At the risk of slightly labouring the point (this has been covered
before), and with it being unlikely this is your root issue, you're
missing the O_SYNC flag from the /dev/mem which means it's possible
that you're reading the hardware via the processor's data cache (which
is out of date w.r.t. the hardware most of the time).

I don't have any further information on the modem I'm afraid, but
having been bitted by the lack of O_STAT flag I felt qualified to pipe
up on that subject at least! :)
