A modest Error (I mean Proposal)

[Arinte]

I am getting this weird error???
Traceback (innermost last):
  File "Beer", line 17, in ?
  File "D:\POSSApps\anotherposs app\PossDevice.py", line 37, in IOCTL
    if type(command)==type(2):
TypeError: len() of unsized object

Here is the code for the function it craps out on...

 def IOCTL(self, command, dargs):
  command1 = long(0)
  if type(command)==type(2):
   poss.write("IOCTL was int")
   command1 = long(command)
   poss.write("IOCTL Set to Long");
  else:
   if type(command) == type("  "):
    poss.write("IOCTL was a string")
    command1 = command
   else:
    if type(command)!=type(2L):
     poss.write("IOCTL fail")
     return -1
  self.dump();
  poss.IOCtl(self.devname,command1,dargs) #make this pass the ioctl command
as an PossArg with a special name
  return 0

This is part of a middle class between my C++ program and the user written
python code.
