Baseband monitoring

Hello there, Could anyone help me with the following, please: Is there any way to monitor baseband via OS? I.e. when the GSM modem receives some communication from the network and such communication is "addressed" to SIM (e.g. RAND), can we use OS to either (a) "see" that communication from the network, or (b) at least know that some communication of certain type was received by the modem and passed on to SIM? Many thanks in advance for your time and consideration! Alexander
