Hi Andrei,

SIMtrace 1 displays the ATR on the console output:
Entering main loop
ATR APDU: 3b 9f 96 80 1f c7 80 31 a0 73 be 21 13 67 43 20 07 18 00 00 01 a5 

and sends it in as GSMTAP APDU data packet:
020404000000000000000000000000003b9f96801fc78031a073be21136743200718000001a5

SIMtrace 2 also displays the ATR on the console output:
Entering main loop
Card state change: reset release
ATR: 3b 9f 96 80 1f c7 80 31 a0 73 be 21 13 67 43 20 07 18 00 00 01 a5 

but does not sent it over GSMTAP, since this is not really an APDU.

Let me fix that quickly and I will let you know once the change is merged.

Kevin
