Subject: Problem with elComandante Keithley client during full qualification 
Full qualification was attempted for M1532 on Oct. 1. After the second Fulltest at -20 C finished, the Keitley client crashed with the following error
  File "/home/l_tester/L1_SW/elComandante/keithleyClient/keithleyInterface.py", line 147, in check_busy
    self.check_busy(data[1:])
  File "/home/l_tester/L1_SW/elComandante/keithleyClient/keithleyInterface.py", line 147, in check_busy
    self.check_busy(data[1:])
  File "/home/l_tester/L1_SW/elComandante/keithleyClient/keithleyInterface.py", line 147, in check_busy
    self.check_busy(data[1:])
  File "/home/l_tester/L1_SW/elComandante/keithleyClient/keithleyInterface.py", line 147, in check_busy
    self.check_busy(data[1:])
  File "/home/l_tester/L1_SW/elComandante/keithleyClient/keithleyInterface.py", line 147, in check_busy
    self.check_busy(data[1:])
  File "/home/l_tester/L1_SW/elComandante/keithleyClient/keithleyInterface.py", line 147, in check_busy
    self.check_busy(data[1:])
  File "/home/l_tester/L1_SW/elComandante/keithleyClient/keithleyInterface.py", line 139, in check_busy
    if data[0] == '\x11': # XON
RuntimeError: maximum recursion depth exceeded in cmp

Because of this, the IV measurement never started (the main elComandante process was simply hanging and waiting for the Keithley client to report it's ready) and the main elComandante process had to be interrupted.
