 Michal, would you be OK with this? Is your

That's right. It is my mistake. SAP APDU Requests mapping to SIM commands, so
there is no problem to determine which side is modem/server. So we can drop
this functionality.

Yes, thanks for you help. I guess you can apply your patch.

Hmm... I miss example logs for SAP, so here you are. May you can check why
gsm-sim dissector does not correct decoding all frames. For example 112
(malformed) or 115 (skip some bytes)
