Fixed in https://gerrit.osmocom.org/c/pysim/+/35230 but now we get a new exception, at least on the SJA5-9FV:

- % Done changed from 30 to 90
The P1/P2 of DF21 is explicitly listed in Section 4.1.1 of https://globalplatform.org/wp-content/uploads/2014/10/GPD_SE_Access_Control_v1.1.pdf
Sends the configuration of the device Access Control Enforcer and requests the configuration of the ARA-M
I think it's "just" that the ARA-M applet from Bertrand Martel doesn't support this. And indeed https://github.com/bertrandmartel/aram-applet confirms this. So the new exception regarding status word is not a bug in pysim, but a limitation of the ARA-M applet.
