PS. With all the other sscanf()s updated, it works:

# /opt/ITmuscle/bin/gpshell list-cflex.txt
mode_201
enable_trace
establish_context
card_connect
* reader name Sun Blade Internal Reader 00 00
select -AID a0000000030000
dummy contains: a0000000030000
Scanned: 0xffffffa0
Scanned: 0x00
Scanned: 0x00
Scanned: 0x00
Scanned: 0x03
Scanned: 0x00

before call to select_application(), AID contains:
  0xffffffa0
  0x00
  0x00
  0x00
  0x03
  0x00
