( https://gerrit.osmocom.org/c/pysim/+/35161?usp=email ) Change subject: pySim-shell: Do not use self.lchan.scc when sending raw APDUs. ...................................................................... pySim-shell: Do not use self.lchan.scc when sending raw APDUs. When sending raw APDUs, we access the scc (SimCardCommands) object via the scc member in the lchan object. Unfortunately self.lchan will not be populated when the rs (RuntimeState) object is missing. This is in particular the case when no profile could be detected for the card, which is a common situation when we boostrap an unprovisioned card. So let's access the scc object through the card object. This is also more logical since when we send raw APDUs we work below the level of logical channels.
