How to display RIL communications (RIL_REQUEST_SIM_TRANSMIT_APDU_CHANNEL)

[TazKilla]

Hello all,

I'm trying to debug my app, and I need more logs informations.
When I read radio buffer logs, I only found factual infos, like RIL_REQUEST_SIM_OPEN_CHANNEL, or RIL_REQUEST_SIM_TRANSMIT_APDU_CHANNEL. What I need is to know the content of those requests.
I'm already looking in the android source code (around ril.cpp, in platform_hardware_ril), but there is a lot of lines to read :0
Below are some logs, for example:

Thanks in advance for you help, and sorry for my poor english.
