Description

In the test setup at my home office, I can occasionally see osmo-remsim-client-st2 get stuck when the Modem (in this case a Quectel EC20) is performing PTS with the card.

In the log of osmo-remsim-client-st2 I can see:

SIMtrace => PTS req: ff 10 94 7b 00 00 ^M
SIMtrace -> 01 07 00 00 00 00 15 00 04 ff 10 94 7b 00 00 ff 10 94 7b ^M
SIMtrace => PTS req: ff 10 94 7b 00 00 ^M
SIMtrace IRQ 01 04 00 00 00 00 15 00 13 00 00 00 00 00 09 04 0a 80 25 00 00 ^M

after which the communication doens't proceed. After a long time, the modem seems to retry without PTS and then proceeds with normal SIM card communication.

The SIM Card ATR in this case is 3b7d9400005555530a7486930b247c4d5468.
