Ah.  At the moment blacklisting specific ports isn't possible and
there's no way to have MM only control the data connection but not for
example SMS, because the secondary port is used for status and control
while the main port is used for PPP.  That said, if the modem has more
than two AT-capable ports, MM will only use two of those ports and just
won't open the other ports, so your program could use those after
probing.
